  • en Oxygen: The terraforming of Earth

  • (Picture by Alexander Gerst from the ISS)

    We take good old O2 for granted. People are always going on about how early Earth was “perfect” for life. A perfect hell maybe. No ozone layer, no oxygen, extreme heat, an abundance of highly corrosive chemicals in the atmosphere including sulfur and methane.

    Much like found on Titan the largest of the moons of Jupiter today. It was a literal red sky hell. With all of that methane and sulfur, it must have smelled like a frat house on chili and hard boiled egg night. So, the Earth was devoid of oxygen in the beginning but as I said there was a metric butt-load of methane and sulfur in the oceans.

    So, little single-celled organisms developed that lived on methane and sulfur. After a while, the sulfur level dropped and the methane level did as well. No one is sure why. There still was little oxygen. So some more little critters evolved which produced oxygen called “cyanobacteria”.

    It took a billion years for these critters to terraform our planet for the evolution of animals and more complex plants. To this day all plants incorporate these ancient cyanobacteria into their cells in structures known as a “cyanoplasts”. You see life itself changed the planet to support life.

    This is what life does.

  • en modern 5F1 with Boothill kit and Mergili cabinet

  • I found this well built 10″ 5F1 amp on ebay last month and grabbed it off for very good price. but there were few stuff I don’t like and replaced them today. and I’m waiting for the yellow and red Jupiter 0.022uf coupling caps. hope not to heat up the soldering iron after the coupling caps.

    I have replaced the filter caps, speaker wires along with the 1/4 plug. and few more like the tubes, handle, and a couple of the wires.

    it’s the first modern tweed cabinet which I like. it sounds great with this WGS ceramic speaker. I see why people recommended this speaker for champ. I’ve been biased toward alnico speakers so far. and this speaker changed it a bit.

     

    the orange filter caps are Roederstein 33uf 450v which replaced the stock caps from the kit. I didn’t know the limit of 5y3 and was brave enough to put two of them on it. then realized the rectifier was too hot and went to 33+10+10. 33uf right next to the rectifier seems fine so far. I’ve tried on the original tweed amps without an issue before.

    this amp is dead quiet and the filament wiring is a bit different to the original champ. I’m trying to figuring out it. nothing is easy with electric circuit even 5F1 is this simple.

    I have some NOS Sprague black beauty caps and I expected something vintage with them. but I’ve learned they are not useful as the coupling caps. they were good as the guitar tone caps. but they dramatically reduced the output volume regardless of the values. realized why my 18watt replica’s output volume was that low 15 years ago today. I’m still wondering why anyway. 

    [update] the sprague caps I put on this amp had twice high capacitance than the spec. the caps were fine.

     

    Wow. The amp looks in really good shape. Or did you clean it by yourself?

    I remember you talked about Shellac a couple of months ago. I knew you’d interested in this cabinet. and this one meets your standard I guess.

    I’ve seen a few different tweed replica cabinets before and this piece is the best so far. this cab sings like the old tweed amps and will be getting better over time.

    Shellac coating gives every wood surface a “special” touch. I once learned its application during my apprenticeship training back then. But haven’t applied since then, also it is time consuming and expensive.

    the Heyboer HTS-12005 power transformer is a bit different to the usual 5F1 PT. B+ is 420V with RCA and GE 5y3, and 422V with Bendix. it’s hot while B+ is about 340V on 5F1. the B+ on my ’59 champ is 320V and I remember I’ve read about vintage champ with 360V B+ on somewhere before.

    Boothill amp says it’s OK and I remember I built a couple of 18watt replica very hot biased with Heyboer transformers a while ago. 

    but I’m wondering if it’s fine with 5v4g. B+ is 437V with 5v4g on this 5F1. I’ll check the plate voltage tonight.

    it’s my final, I hope, setup with 22+22+10 filter caps which have almost zero 60hz hum. the black beauty caps are 0.01uf marked on it. and they actually are around 0.02uf. I’m wondering how the sound goes while and after breaking in if it’s true on my coupling caps on my 5F1 in 5E3 size cabinet.

    Due to the heavy bombing in World War II, #Magdeburg has less to offer in terms of cultural attractions than other cities of the same size. But of course there are still enough things to look at and the Hundertwasserhaus is without question one of real gems. Shortly thereafter follows the Magdeburg Cathedral, also a special landmark of the city.

    I remember the word “wasser” means water. and haus sounds like house. what’s the meaning of Hundertwasserhaus?

  • en Tecumseh

  • Tecumseh, one of the greatest men ever to be born on the American continent. A Native American, war chief and statesman he was essentially a Native American George Washington. He saw his family killed by the white settlers and the soldiers of the new United States of America yet he refused to kill women and children.

    Among the tribes, there was no concept of Indians as a group i.e. you were a Shawnee or Mohawk, not an Indian. Indeed, even the whites were seen as “tribes” the British tribe, French tribe, Spanish tribe or, worst of all from their perspective, the American tribe. Tecumseh was a visionary and envisioned a Native American confederacy from the Great Lakes to the Gulf.

    He sided with the British in the War of 1812 only to be abandoned after the end of the war. Abandoned to the Americans who destroyed him and his people.

    Please note: No nation is all good or all evil. One must acknowledge the failings as well as the successes of a nation to truly understand it.

  • en The five principles: Wisdom of the Axial Age

  • These five principles form the foundation of just about every major religion and philosophical system which emerged in that incredible span of years from the 8th to the 3rd century BCE called the Axial Age when Taoism, Buddhism, Zoroastrianism, Confucianism, Classic Greek Philosophy, and Christianity all flowered in the same time period. Why? Simple, it is because they are universal and when put into active practice in our daily lives they work.

    The practice of these principles will garb you in a suit of spiritual armor. Even in the midst of chaos and in the face of evil your heart will be unsullied, calm and serene.

    The five principles: Wisdom of the Axial Age

    1. Be compassionate. Compassionate in both thought and deed. Learn to recognize that the actions of others are often caused by spiritual pain. Avoid contempt. Avoid those mental judgments we always make of others. Compassion leads to harmony and harmony and balance is the key to inner peace.

    2. Be kind. Very simple. In every interaction, you have you have an opportunity to add to the sum total of good. No act of kindness or charity is too small. It does not matter if you receive gratitude. At times your acts of kindness will even cause resentment in others. That is their way. Let yours be kindness.

    3. Be Forgiving: Forgive others and mostly yourself. Forgiveness is not easy. It requires effort to let past harms and slights go. You may be perfectly justified in your anger, sorrow or resentment but it does not matter. Resentments do not harm the object of your resentment. They harm only you. Much of our spiritual disharmony is caused by our own self-contempt. We magnify our failings. We mull over our mistakes and shortcomings again and again. We compare ourselves to an impossible ideal and then hate ourselves when we fail to measure up. Forgive yourself. Let it go. There is so much that is good in you and tomorrow brings a new opportunity to achieve your dreams.

    4. Be Loving. When you have been compassionate, kind and forgiving you will sense a flood of a unique form of love. Love of all. It will well up within you and influence your every action. It will baffle and confuse others. People who would confront you, engage you in argument or dispute and who would transmit their own anger to you will be astounded when they see that you are unruffled. They will not know what to do. Your calm and peace will affect them.

    5. Be Accepting: You are not in control of the universe. Stop taking everything so personally. It is not all about you. Be humble before the majesty of the universe knowing that it is you and you are it. Things are often not going to go your way. You may be treated unfairly by others, or be the target of hatred or cruelty. You are not going to get everything you want. Accept this. Move on.

  • en Your universe is just a pattern of nerve fibers in the “black box” of your skull.

  • You think that the universe resides outside of you and it is true that there is something out there all right. However, that something is nothing like your perception of things. Let’s take the materialist view. That is that everything is just “stuff”. Atoms, molecules, quarks and radishes and all kinds of other “stuff”. That stuff is a kind of vibratory energy through which other kinds of energy flow. Energy is likewise “stuff” just in a different form.

    Your brain for all of its gooey gray grossness is a pretty complex thing. More complex than just about anything else in the universe. Stars and planetary systems are BIG but relatively simple. Now, within this gray matter are trillions perhaps a hundred trillion or more neurons. These are specialized cells. They are connected with neural pathways like a gigantic and complex net. When we observe we make pathways. When we think we make other pathways in exactly the same fashion except that the data comes from the brain, i.e. the pathways that are already present.

    The brain forging neural networks in real time.

    Now, everything you know, remember and experience has no existence for you aside from patterns in this network which began to form the instant your brain developed enough in the womb. So, all of your experiences are just patterns. If the patterns were changed, as in an accident then your reality changes. It is all just patterns connecting and relating to other patterns in this neural network. This is thought, cognition and self-awareness on a macro scale.

    Yet, reality, objective reality is something else altogether. It has an extrinsic existence outside of this pattern of neural networks. Your knowledge of it is very limited. Just enough to get around, find food shelter and a mate. When you sleep something else happens. The network fires in patterns. Not random patterns. Very meaningful patterns but without the necessity of obeying the laws of time, space or physics.

    Consciousness is so much more complex than even the greatest neuroscientists, medical researchers and philosophers can even begin to grasp and the waking mind is the least significant part of the picture.

  • ko 사파리에 오른쪽 탭 닫기 기능 추가 – 모하비 기준

  • 크롬은 오른쪽 탭 닫기 기능이 있습니다. 쓰다보면 꽤 편한데 사파리에는 이 기능이 없습니다. Automator를 이용해서 간단하게 구현이 가능합니다. 저는 영문메뉴를 사용하지만 스크린샷을 보면 어렵지 않게 할 수 있을겁니다.

     

    AutomatorQuick Action 을 선택합니다.

    Action 종류는 Run AppleScript, Application은 Safari 를 선택합니다.

    아래 링크로 이동해서 해당 코드를 복사해서 넣습니다.

    http://awhite.ca/2014/01/close-tabs-to-the-right-for-safari/

    코드를 복사한 상태에서 사파리에서 탭을 몇개 띄웁니다.

    Automator로 돌아가서 오른쪽 상단의 실행(▶︎)을 누릅니다. 사파리의 활성화된 탭 오른쪽 탭들이 닫히는 걸 확인할 수 있습니다.

    이제 해당 Quick Action 을 저장합니다. 저는 크롬 메뉴를 그대로 썼습니다. Close Tabs to the Right

    Safari – Services 메뉴에서 이제 확인이 가능합니다. 역시 눌러보면 오른쪽 탭들이 닫힙니다.

    키보드 단축기를 등록합니다. 이름은 사파리의 Services와 동일하게 하구요. 주의할 점은 All Controls가 선택되어 있어야 합니다. Text boxes and lists only 로 되어 있으면 동작하지 않습니다.

     

    참고 – 간혹 실수로 열두어야 할 탭을 닫을 수 있습니다. 탭의 맨 오른쪽에 보면 + 버튼이 있습니다. 그냥 누르면 새 탭이 열리구요. 이걸 누르고 기다리면 닫은 탭 리스트가 나옵니다.

  • ko 12ax7 진공관 몇가지와 트위드 앰프

  • 며칠전 트위드 챔프에 있던 50년대 후반 RCA 12ax7 관을 하나 깨먹었습니다. 진공관 찾으러 박스도 몇번 뒤지고, 친구네서 하나 얻어오고,  소리전자 중고장터에서 하나 샀습니다.

     

     

    맨 왼쪽에 Amperex bugle boy는 교과서 같습니다. 얘하고 깨진 RCA 블랙플레이트가 제일 좋아하던 한쌍이었습니다. 중간에 실바니아하고 GE는 구하기 쉽고 상대적으로 가격이 저렴한 실바니아 롱플레이트와 GE 숏플레이트입니다.

    필요한 12ax7은 세개인데, 제대로 소리가 나는건 두개라서 시세도 알아보고 써본 진공관을 머리 속으로 정리하고 있습니다.

    JJ는 롱플레이트라서 마이크로포닉 가능성이 있다는 얘기를 들은 적이 있었습니다. 그리고 최근에 경험했습니다. 처음에는 챔프에서만 그러더니 딜럭스에서도 발진이 있었습니다. 관이 죽어가던 중이었나봅니다. 우연히, 소브텍은 12ay7 하나가 그러구요. 오래 전에도 이런 적이 있었습니다. 아래 비디오에 있는 증상입니다. 처음에는 어디서 겪어본 일처럼 멀더니 하니씩 기억이 나네요. 기억도 주파수나 바이어스가 있다고 종종 느낍니다.

    마이크로포닉이 있는 관은 실드캡을 여부에 따라서 그 정도 차이가 있었습니다. 관 문제가 아니고 필터캡에 문제가 있어서 그랬던 경우도 있습니다. 덕분에 발견해서 교체를 했구요. 챔프는 6v6 한개 5w 싱글엔디드, 딜럭스는 6v6 두개 12w 푸시풀입니다. 싱글엔디드가 푸시풀에 비해서 60hz 험, 그리고 프리관 마이크로포닉에 약합니다. SE와 PP의 이런 성향이 일반적인 것으로 알고 있구요.

     

    지금까지 써본 12ax7을 기억에서 꺼내보면 이렇습니다. 아직 망가진 관들도 몇개는 그대로 가지고 있습니다.

    – 암페렉스 12ax7 은 앰프를 새것처럼 느끼게 합니다. 단단하고 선명합니다. 해상도라는 단어가 자연스럽게 떠오릅니다. 어떤 앰프에 넣어도 그렇습니다. 마찰음이 좋아서 기타 연주의 터치감, Ella Fitzgerald 목소리나 관악기의 오버드라이브가 느껴지게 합니다. 저에게는 12ax7 = Amperex 이렇게 되어 있습니다. 암페렉스 12ax7 장점 중 하나는, 저렴하 가격입니다. 모회사인 필립스를 비롯해서 여러 상표로 팔렸습니다. 그리고 같은 관인데 Bugle Boy 마크가 있으면 더 비싸더라구요. 이런걸 무시하고 ebay에서 12ax7 Holland로 검색하면 가격대가 낮아집니다.

     

    – 소브텍 12ax7wa 90년대 만들어진 것이 하나 있습니다. W는 내구성 기준으로 붙습니다. W가 붙으면 산업용, 혹은 군용 표시인데 과거나 지금이나 실제로 의미가 있는 것 같지 않습니다. 소브텍, EH 상표가 붙은 소브텍, 신형 JJ 관은 일반적인 숏 플레이트보다도 플레이트가 짧습니다. 이 구조에서 오는 특징이 있을텐데 소브텍 관을 꺼내서 다시 업데이트하겠습니다.

     

    – (나중에 추가한 내용입니다) 12ax7wa 는 실바니아, GE, 롱플레이트, 숏 플레이트 모두 흔합니다. 개인적인 경험에서 6,70년대 이 두회사의 12ax7wa 역시 특별한 기억은 없습니다. 저는 “무난한 미국관” 이라는 개인적인 분류가 있습니다. 예열 충분하고 볼륨이 적당하면 누구나 좋아하는 음색과 질감이 있습니다. 숏플레이트가 무난합니다. 롱플레이트는 좋을수도 아닐 수도 있었습니다.

     

    – 요즘은 별로 안보이던데 유고슬라비아 Ei 12ax7을 제법 가지고 있었습니다. 아직 가진게 있나 싶어서 진공관이 들어있던 박스를 다 꺼내봤는데 없더라구요. 일찍 죽은 기억도 없고, 흔하던 시절에 만족하고 썼습니다. Ei는 텔레풍켄의 설비로 만들었다고 하는데, 비슷한 시기의 RFT나 Ei는 그래서 꾸준히 인기가 있나봅니다. RFT는 늘 궁금한데 기회가 없었습니다. 악기포럼에서의 객관적인 평가는 늘 좋더라구요.

     

    – RCA가 만든 진공관 규격이 많습니다. 12ax7도 그렇습니다. 40년대부터 생산했고, 50년대 펜더나 다른 앰프들도 RCA 관을 많이 사용했습니다. 저한테 암페렉스하고 더불어서 제일 좋은 관입니다. 50년대 만들어진 블랙 숏플레이트 RCA 12ax7은 암페렉스하고 비교하면 예열이 조금 더 늦고, 대신 달궈지고 나면 돌덩어리 같은 입자감이 있습니다. RCA 블랙플레이트 관의 성격은 다른 관하고 제법 다릅니다. 극단적인 비교이기는 한데, 암페렉스는 잘 만들어진 엔진이나 로봇을 떠올리게 하고, RCA에서 불꽃을 떠올립니다.

     

    – 12ax7의 실로폰, 혹은 종소리

    나무로 된 전통적인 실로폰 소리를 들으면 나무와 나무가 만나는 순간에 때리는 소리하고 종소리처럼 예쁜 고음이 들립니다. 저는 기타의 톤을 줄이거나 드라이브를 높이면 트럼펫과 트럼본을 떠올립니니다. 기타나 앰프의 sweet spot에서는 이런 금관악기 소리하고 나무 실로폰 소리를 같이 듣습니다.

    이런 밸런스를 앰프에서 들으려면 예열이 되어야 하고, 진공관의 성향도 그 이후에 선명해집니다. 회로가 단순하고 출력이 낮은 챔프나 딜럭스는 프리관 성격이 잘 느껴집니다. 챔프가 유난히 그렇습니다.

    5와트 챔프 5F1은 정류관, 6v6 파워관, 12ax7 각 하나씩입니다. 정류관은 원래 다 비슷하고, 파워관 오래 쓴것과 새것과 비교해도 별 차이가 없습니다. 어떤 프리관을 넣어도 다 좋은데, 암페렉스는 넣고 전원만 넣어도 이미 다른 관 예열된 음량입니다. 그리고 예열되면 다시 더 대역하고 음량이 커집니다. 저음은 언제나 단단합니다. 미국관은 앰프가 충분히 달궈진 이후에 제 소리가 납니다. 잠깐 들어봐서는 알 수 없습니다.

     

    – 저는 GE하고 Sylvania는 묶어서 보게 되었습니다. 제가 써본 두 회사의 관은 아무 문제가 없이 평범하거나, 선명하고 거친 질감이 앰프가 충분히 달궈진 다음에 나옵니다. 그런데 잘 안나오는 애들도 있더라구요. 미드레인지가 강해서 초반에는 먹먹하다 싶은 경우도 있습니다. 앰프 성향에 따라서 매력적이거나 그렇지 않거나 했습니다.

    암페렉스 12ax7을 주로 쓰게되는 이유중 하나가, 확율과 가격 문제입니다. 내구성이 더 좋은건지 90% 이상이면 밸런스와 음량이 다 좋습니다. 

    하루 종일 매일 쓴다고 해도 몇십년 쓸 기준으로 찾다보면 구관을 쓰게 됩니다. 이미 신관은 수명이 현저하게 짧은걸 경험해서 아예 생각을 안하게 됩니다. 

    최근 ebay 시세를 봤습니다. 지금 시점에서 100~110%에 외형과 핀이 깨끗한 NOS, 혹은 상태와 수치 좋은 중고 12ax7을 구하려면 개당 100불 전후로 텔레풍켄(Telefunken), 멀라드(Mullard), 텅솔(Tung-sol), RCA, 암페렉스(Amperex) 정도가 나옵니다. RCA는 이제 남은게 별로 없어서 그런지 하루하루 가격이 올라갑니다.

    그 반 가격인 50에서 그 이하로 내려가면, 주황색이거나 다른 상표를 단 암페렉스, RCA 숏플레이트가 주로 보입니다. RFT는 많이들 권하는데 궁금하기는 합니다.

    25불로 목표치를 잡으면 수치가 90% 이상이고 삼극관의 양쪽 수치가 비슷한 실바이나, GE 등등이 보입니다. 이렇게 구한 GE 12ax7 하나가 있습니다. 처음에는 잘 몰랐는데 며칠 써보니 챔프하고 궁합도 좋고 바로 켜면 벙벙거리는 소리가 10분 20분 지날수록 단단해지면서 마음에 들었습니다. 프리관도 예열하고 상관이 있는건지, 아니면 미국관들은 트랜스포머나 회로가 뜨거워진 상태를 기준으로 프리관을 만든건지, 그냥 그런건지 궁금하기도 합니다.

     

    – 부록입니다. 최근에 5y3와 6v6 가격을 좀 알아봤습니다. ebay에서 경매나 offer로 실제 거래되는 가격입니다.

    5Y5GT – RCA, Sylvania가 많고 GE도 많습니다. 20~25불 정도입니다. 사용기간이 몇십년 차이나는 RCA, GE 5y3를 몇개 사용해봤는데 5w SE나 12w PP 에서는 차이가 없었습니다.

    프리관이나 파워관에 비해 수명이 길어서 그런지 가격이 비싸지 않습니다.

     

    6V6GT – 역시 RCA, Sylvania, GE가 많습니다. Tung-sol 도 미국회사라 그런지 많구요. NOS 관은 처음 사서 처음부터 떵떵 울리기도 하고, 하루 이틀 쓰고 나서야 제 음량이 나오기도 했습니다. 

    역시 개당 20불에서 25불입니다. 왼쪽부터 캐나다산 GE, 오른쪽은 생산시기가 다른 것으로 보이는 실바니아 6v6 입니다. 안을 들여다 보면 구조가 조금씩 다릅니다. 그렇지만 프리관처럼 성향이 크게 다르지 않습니다. RCA 먹관도 하나 가지고 있습니다. 역시 큰 차이는 없었습니다.

    복각 앰프에 따라온 RCA 그레이 플레이트가 생겼습니다. B+ 전압이 320V인 빈티지 앰프와 420V인 복각앰프 모두에서 50년대 RCA 블랙플레이트와 비슷한 소리가 납니다. 음량은 암페렉스와 비슷합니다.

    플레이트는 측면에 작은 구멍이 없다는 걸 제외하면 암페렉스와 거의 똑같이 생겼구요. 마킹은 12ax7a 입니다. RCA 숏 플레이트는 늘 좋네요.

    사진에 있는 세가지만 비교하면,

    암페렉스는 단단하고 퍼짐 없는 저음, RCA는 찰랑거리는 고음, GE는 다크한 맛의 강조된 미드레인지가 좋습니다.

    모두 5F1 챔프 기준입니다. 같은 회로에서 B+ 전압이 낮은 앰프에서는 GE가 마음에 들고, 높은 앰프에서는 GE의 미드레인지가 너무 강해서 나머지 두개가 마음에 들고 그렇네요. 

    제 경험 안에서는 숏플레이트가 어떤 앰프하고나 잘 어울립니다.

  • en I’m into 5v4g than 5y3 with 6v6 tweed amps

  • [EDIT]

    I’m updating this post not to make people confused. I believed B+ is lower with 5v4g than 5y3. but 5v4g is increasing B+ and makes the bias warmer than 5y3. I guess it is the reason I feel the amps are more alive with 5v4g

    and, I noticed the vintage amps still have the original caps from 50’s and early 60’s are more vulnerable with 60hz hum. I’m just guessing leakage of the coupling caps and the filter caps could be the reason. I’m still enjoying 5v4g with the amps with new components. and didn’t have an issue with my 5D3 which has new filter caps. the old Astron coupling caps are still fine with the DC leakage in it. 

    there are more info for 5vg and 5y3 rectifiers on the gearpage.net the people there have more and better info

    https://www.thegearpage.net/board/index.php?threads/swapping-rectifier-tubes-5ar4-vs-5r4-vs-5v4-vs-5y3.1382681/

     

    I hook up tweed champ, deluxe, and m-track 2×2 together while I’m playing with youtube music. 5v4g sounds still alive with this stereo and digital setup to me. m-track 2×2 is sharing the one single full bandwidth for usb and instrument input. it sounds good only when you turn the knob to USB or Direct. it sucks when the knob is the center. maybe it’s the reason it’s cheap. 

    it’s the knob on m-track 2×2. don’t buy it if you want to use your guitar amps as monitor speakers and, still for your guitar at the same time. maybe I’m just doing this wrong. 

    0 6 days ago

    tried 5v4g with this modern 5F1 with 10″ ceramic speaker in 5e3 cabinet. and it seems to be the right place for it. I prefer 5v4g with tweed deluxe to tweed champ. it could be the size of the cabinet and the speaker I guess from this setup. 

    one good thing with modern 5f1 is all the components are new or NOS and it has almost zero 60hz hum. I’m going to exchange 2 prong cable to 3 prong on my old champ and try 5v4g again with it.

  • en gathering information on vintage tweed champ output transformer

  • while I’m working on a tweed champ 5f1 replica with 10″ speaker, I recall they say the output transformers affect the tone.

    and, I noticed I never saw the back side of champ chassis before. it’s where I start finding a vintage OT for my replica.

     

    0 on April 1, 2019

    the secondary OT has ground to the frame. and RCA connector is soldered like this. vintage fender tweed like champ, deluxe, and tremolux seemed to have the same ground like mine.

    I got confused with the primary impedance of this OT. this data sheet on classictone.com has the right dimension of it. the primary impedance is 17K here. and it’s 5K on mojotone’s page

    http://www.classictone.net/40-18110.pdf

    https://www.mojotone.com/amp-parts/Output-Transformers/Tweed-Champ-Style-NOS-Output-Transformer

    they probably have the different sources of the original transformers I guess. anyway, it’s the dimension. 1 3/4 width, and 1 7/16 height just like the classic tone’s spec. it’s 42.5mm x 35mm in metric on my double sided hoechstmass tape measure.

    tdpri forum and the members helped a lot since I got this champ. then again this time.

    http://www.tdpri.com/threads/which-amp-would-you-chose-for-an-1950-broadcaster.355052/page-2

    tweed princeton and champ are both 5w. and shared the transformers. mine has 106 and the member seems to be an expert with experience advices to try 107 which is larger than 110, 105, and 106.

    maybe it’s the reason the replacement transformers have different primary impedance. but I still don’t get which one is correct for 5F1 or how the different ratio affects the tone on the same circuit.

    this 1962 champ came with an OT marked 125A3A on it. and the size looks identical to Triad 106. 

    these two different 5F1’s sound quite different with the same tubes and the speaker. and I assume the yellow Astron and the blue Ajax are one of the minor differences. I thought the major difference came from the cabinet wood like the guitars. but, I’m not sure anymore. 

    I’ll dig more on the OT’s later.

    didn’t have a luck for vintage Triad OT. but found these two from Stancor. A-3877 is 5K to 4ohm, and A-3878 is 7K to 4ohm. they both are 5 watts rated.

    they are Heyboer PT and Classictone OT. both are slightly bigger than the original transformers. Classictone 40-18030 has two primary input tabs which are 5k and 8K. I tried them both but didn’t see a noticeable difference today. it was too late to turn up the volume enough to feel the difference. I simply went to 8k which is told hot and close to the vintage champ OT.

    5k seems like the ideal spec. by the document and calculation. but 5F1 had 7k to 17k primary input from my research.

  • en Question to the Slowbean community. (Stone / rock processing)

  • Hi community, since a long time I’m pondering about two topics that interest me. Stones / rocks and their industrial processing. If I want to cut rocks or slice stones in small pieces I have to use large machines, the energy consumption of such stone cutting machine is way too high for somebody who would just start to cut / slice rock. So, my question is: Do you have any ideas, thoughts or know about eco-friendly techologies which are energy efficient for cutting rocks into small slices? Every input regarding this topic is welcome.

    5 on April 10, 2019

    I believe some would light on the shed eventually. hope it works soon.

    on April 10, 2019

    Yes, I am certain that somebody will have a cool idea. I do not plan anything regarding the topic above but there are so many stones and rocks lying around in the nature, and there is always a purpose to make something out of them. For artworks, homes or just as deco.

    on April 11, 2019

    I’ve been thinking about this for the last couple of days. blade saw is the first idea we can have, with motor and battery. they are common and you probably want more than the high efficient batteries and brushless motors.

    then high frequency metal strings came to my mind. have anyone tried this before? or is it already on the market?

    and I remember a weapon grade water jet nozzle on youtube I watched before. 

    what’s your idea in your mind? echo-friendly means even you need to take care of the fine dust from the process from my understanding. 

    on April 13, 2019

    Actually have researched such water jets last night and it seems these devices are beneficial. Just have to  get in touch with a stonemason, to see how they work. Perhaps a blade saw / machine which is connected to batteries that are fueled by a eco-friendly energy source.

    on April 13, 2019

    google’s content based ADs seems to work somehow. I see “diamond wire loop” AD on this page. 

    on April 14, 2019

    Now they just need to show what the future has to offer. 😉 Anyway, while I was researching the above topic I came across of a designer / inventor who does 3D printing with sand (from deserts) using the power of the sun. His name is Markus Kayser and his “solar sinter” is simply crazy!

  • de In der Stadt Wurzeln schlagen: Urban Gardening

  • Früher galt der Laubenpieper mit seinem Schrebergarten als Inbegriff der Spießigkeit. Diese Zeiten sind vorbei: In den Städten dieser Welt wird an allen möglichen und unmöglichen Orten gepflanzt und geerntet. Allein oder in der Gruppe. Auf städtischen Brachen oder Grünstreifen, auf privaten Dächern. Ob Blumen oder Nutzpflanzen – mit jedem Beet wird wieder ein Stück Natur in die Stadt geholt. Urban Gardening liegt im Trend.


    (Photo: The Home Garden in Sydney, Australia)

    Der Boom der Gärten im Stadtgebiet ist nicht mehr zu übersehen. Die Stiftung Interkultur z. B. betreibt interkulturelle Gärten, in denen Deutsche und Menschen von anderswo zusammen Zucchini säen und Erbsen ernten. 2003 waren es fünf Projekte, 2012 sind daraus mehr als 100 geworden – Tendenz weiter steigend.

    Die Motive, die hinter Urban Gardening stehen, sind dabei vielfältig: Mal geht es um ökologische Aspekte wie die nachhaltige Bewirtschaftung der gärtnerischen Kulturen, die umweltschonende Produktion und den bewussten Konsum landwirtschaftlicher Erzeugnisse, mal geht es um dringende gesellschaftliche Anliegen wie Armutsbekämpfung, Flucht aus ländlichen Bürgerkriegsregionen in sichere Städte oder die Befriedung von Ganglands.

    (SANAA House & Garden by Jenna Rowe)

    Die Vorteile von Urban Gardening liegen auf der Hand:

    – Lokale Nahrungsmittelherstellung bei gleichzeitigem ortsnahen Konsum verkürzt Transportwege und schont so die Umwelt.
    – Der Einsatz von Gewächshäusern in Verbindung mit smarter Technologie optimiert die Erträge auf begrenzten Anbauflächen und spart Energie.
    – Urban Gardening ermöglicht die Verbindung von Landwirtschaft und städtischer Lebensweise, indem lokal natürliche Stoffkreisläufe durch Recycling von kompostierbaren Abfällen und Abwässern ermöglicht werden.
    – Das steigende Interesse an lokaler Nahrungsmittelproduktion fügt sich ein in eine größere soziale Bewegung, die sich der Bewahrung des Wissens, der Aufwertung und dem Erhalt von lokalen Spezialitäten angenommen hat.
    – Urban Gardening hilft Engpässe in der Versorgung städtischen Raums mit Lebensmitteln zu überbrücken.
    – Die Gärten sind Orte, an denen gesunde Lebensmittel angebaut werden und Natur wieder erfahrbar gemacht wird. Sie sind Experimentierfelder für Zukunftsthemen, können interkulturelle Begegnungen fördern und sinnvolle Beschäftigung in der Postwachstumsgesellschaft ermöglichen.

    Neu ist die Idee von Gärten und landwirtschaftlich genutzten Flächen in Städten nicht: In der Antike und Mittelalter waren eigene Gärten um die Häuser ein fester Bestandteil des Stadtbilds. Auch Klein- bzw. Schrebergärten an den Stadträndern und in Kleingartenkolonien gibt es schon seit dem 19. Jahrhundert. Die typische Arbeitersiedlung hatte einen eigenen Garten – inklusive Tierhaltung.

    Die Wurzeln der urbanen Gartenbewegung liegen jedoch ganz woanders: in den New Yorker Gemeinschaftsgärten der 1970er Jahre. Die sogenannten “Community Gardens” waren – und sind es bis heute – grüne Oasen auf innerstädtischen Brachen mit Blumenbeeten und Gemüseanbau zur Selbstversorgung. Community Gardens oder Gemeinschaftsgärten sind kollektiv betriebene Gärten. Die Flächen dieser Gärten sind meist öffentlich zugänglich. Das Konzept ging jedoch weit darüber hinaus: Hier wurden gärtnerische, ernährungspolitische, ökonomische, soziale, künstlerische und stadtgestalterische Fragen miteinander verknüpft und eine nicht-kommerzielle Gegenkultur entwickelt: interkulturelle Gärten, City Farms, Nachbarschaftsgärten, Kinderbauernhöfe, Schulgärten, Guerilla Gardening. Gemeinsames Lernen, die Vermittlung von Wissen und das Schaffen von Bewusstsein sind weitere zentrale Aspekte dieser Gärten.

    Interkulturelle Gärten sind Gemeinschaftsgärten, in denen Menschen verschiedener Herkunft Obst und Gemüse anbauen. Sie bieten Bildungsangebote, fördern einen internationalen Austausch, sind therapeutische Stätten und Zufluchtsorte. Vor allem die Stiftung Interkultur ist hier aktiv.

    Nachbarschaftsgärten werden von einer Anwohnergemeinschaft betrieben und befinden sich in Höfen, vor oder zwischen den Häusern.

    City Farms und Kinderbauernhöfe sind eine Mischform. Hier werden Nutztiere gehalten (Pferde, Schafe, Ziegen, Hühner etc.) und meistens noch ein Garten betrieben. Angesprochen werden damit vor allem Kinder mit Mitmach-Angeboten wie Reiten, Gärtnern und klassischen Hofarbeiten.

    Guerilla Gardening ist die subversive Variante der Stadtbegrünung: Als Form des politischen Widerstands sind die Guerilla-Gärtner kreativ und mit geringer Ausstattung unterwegs, um in das Stadtbild einzugreifen.

    Die Gärten in den Städten tun jedenfalls Gutes – auf vielen Ebenen. Urbane Landwirtschaft und urbanes Gärtnern bedeuten wertvolle soziale und ökologische Vorteile für die Stadtentwicklung: Aus ökologischer Sicht dienen sie der Verwertung organischer Abfälle, sie reichern die Luft mit Feuchtigkeit an und fangen Regenwasser auf, das sonst ungenutzt in die Kanalisation fließen würde. Große, zusammenhängende grüne Dachflächen können sogar das Stadtklima positiv beeinflussen und extreme Temperaturen ausgleichen. Auch Insekten und andere Stadtbewohner haben etwas von den Gärten, da der Anbau von lokalen Nahrungsmitteln zum Erhalt von Sortenvielfalt und Biodiversität beiträgt. Aus sozialpolitischer Sicht beleben insbesondere gemeinschaftlich genutzte Gärten den öffentlichen Raum und schaffen neue Orte der Begegnung und des Austauschs. Nachbarn lernen sich beim gemeinsamen Buddeln kennen, Menschen verschiedener Kulturkreise tauschen gärtnerisches Wissen und Erfahrungen aus. Im besten Falle wachsen mit den Blumen und Pflanzen die Gemeinschaften, neue Impulse für Kulturen der Teilhabe werden gegeben. Stadtteile gewinnen.

    Nicht zuletzt sind städtische Gärten auch Mini-Modelle für die Städte der Zukunft, in denen Nahrungsmittelanbau und Stadtleben wieder stärker miteinander verwoben werden. Urbane Landwirtschaft schont Umwelt und Ressourcen, indem Transportwege für Nahrungsmittel stark verkürzt werden und von Grünflächen aufgebrochene Betonwüsten leisten einen Beitrag zur Verbesserung der Lebens- und Luftqualität. Für eine Zukunft der Gärten und für lebenswerte Städte sollten kultivierbare Flächen jedoch nicht übergangsweise vergeben oder erkämpft werden müssen, sondern fester Bestandteil einer nachhaltigen Stadtentwicklung werden.

    oh.. I can see what Gärten means without translation. it reminds me of kindergarten as well. 

    on April 14, 2019

    Gärten is the plural of Garten. Never really understood why they didn’t translate “Kindergarten” into an English word. 😂

  • de Keine Zeit?

  • Das Gefühl, keine Zeit zu haben, kennt fast jeder. Zeit scheint mittlerweile ein so begehrter Rohstoff wie Wasser, Erdöl oder seltene Erden zu sein. Der Zeit “hinterherzulaufen”, Zeit zu “sparen” und Zeit zu “gewinnen” ist für viele Menschen zu einem ständigen Lebensgefühl geworden. Stress ist entsprechend als Phänomen allgegenwärtig.

    Erschöpft, ausgebrannt, arbeitsmüde – auch wenn die neue Zivilisationskrankheit Burn-out in Deutschland längst noch kein Massenphänomen geworden ist, greift das Gefühl des Kontrollverlusts um sich. In Japan sind bereits 40 Prozent der Angestellten von einem Burn-out betroffen, Suizide häufen sich. Der Grund: Hier hatte sich über längere Zeit ein gesellschaftlicher Druck aufgebaut, immer mehr zu arbeiten und infolgedessen überhaupt keinen Urlaub mehr zu nehmen, um mehr Zeit für die Arbeit zu haben – mit verheerenden ökonomischen Folgen: da weniger konsumiert wurde, war die Regierung gezwungen, dieser Entwicklung gegenzusteuern.

    Um Zeit zu sparen, reduzierte eine Firma der Geflügel-Industrie in den USA die Toilettenpausen ihrer Arbeiter auf sieben Minuten pro Tag. In Deutschland hat sich der Verbraucherzentrale Bundesverband entschieden, Facebook zu verklagen, weil wir dessen Nutzung, obwohl kostenlos, mit unseren Daten und unserer Zeit bezahlen. In Frankreich ermöglicht das Mathys-Gesetz, Kollegen einen Teil seiner Urlaubstage zu spenden, wenn diese schwerkranke Angehörige betreuen. Ihnen wird mehr Zeit für ihre Familie geschenkt.

    Wie kam es zu dieser Entwicklung, dass wir ständig Zeit sparen und immer noch effizienter sein müssen? Die Antwort: “Zeit ist Geld” – so lautet ein bekanntes Sprichwort, das von Benjamin Franklin stammt und 1748 in seinem Buch “Ratschläge für junge Kaufleute” erstmals auftauchte. Mit dem Kapitalismus wurde Zeit zu einer Handelsware, die gemessen werden muss.

    In der zweiten Hälfte des 19. Jahrhunderts wurde im Zuge der Industrialisierung die Stempeluhr erfunden, um die Produktivität zu steigern und Arbeitsprozessen zu optimieren. 1912 legte das Pariser Observatorium die “Universalzeit” für die ganze Welt fest. Ursprünglich hatte jeder Ort seine eigene als Ortszeit bezeichnete Uhrzeit, die sich nach dem täglichen Gang der Sonne richtete: Wenn die Sonne im Süden ihren höchsten Stand über dem Horizont erreichte, war 12 Uhr. Reisende richteten sich nach der Ortszeit des jeweils erreichten Ortes. Mit der Einführung der Telegrafie und dem Bau längerer Eisenbahnstrecken wurde für deren Betrieb eine einheitliche Zeitangabe erforderlich, die entlang der gesamten Infrastruktur galt.

    Die späteren systematischen Zonenzeiten wurden erstmals nicht von Staaten, sondern von den nordamerikanischen Eisenbahngesellschaften 1883 eingeführt. Die quer über den Kontinent geführten Eisenbahnstrecken erforderten mehrere Standardzeiten. Das weltweite systematische Zeitzonensystem war eine Folge der internationalen Vereinbarung des Greenwicher Meridians als Nullmeridian auf der Internationalen Meridiankonferenz im Jahre 1884 in Washington. Der für die Kartografie wichtige Nullmeridian diente fortan als Bezugsmeridian für die westeuropäische Zeitzone und indirekt für alle 24 weltweiten Zeitzonen. Seit der Standardisierung der Zeit hat die tickende Uhr die Macht über unser Arbeits- und Privatleben übernommen.

    Und Zeit ist kostbar. Das ist Unternehmen schon lange klar. Deshalb verlagern sie Prozesse, die früher von Angestellten erledigt wurden, zum Konsumenten. Ob man das Gepäck alleine aufgibt, seine Möbel selber aufbaut, sich im Selbstbedienungs-Restaurant selber versorgt, sich mit einer Selbstbedienungskasse herumschlägt, Tickets für den Zug am Automaten kauft oder sich selber online berät – überall und zunehmend verrichten wir Arbeit, für die man eigentlich bezahlt werden müsste und investieren unsere Zeit, die dann als Gewinn in die Unternehmensergebnisse einfließt.

    Ein Mensch lebt durchschnittlich 27.000 Tage oder 650.000 Stunden. Lässt sich die Kontrolle über unsere Zeit, diese kostbare und begrenzte Ressource, zurückgewinnen? Oder sind wir dazu verdammt, uns der von anderen diktierten Nutzung unserer Zeit unterzuordnen? Sind wir bereits Sklaven des Gottes Chronos? Welche Strategien gibt es, um wieder die Kontrolle zu erlangen?

    Eine Strategie scheint darin zu bestehen, innerhalb dieses Systems besser und effektiver zu werden. Selbstoptimierung ist ein Trendthema. Bücher zu den Themen Zeit- und Selbstmanagement sind Bestseller. Unzählige Apps wollen uns dabei helfen, Zeit zu sparen. Doch viele dieser Helfer entpuppten sich am Ende nur als weitere Zeitdiebe.

    Oder ist ein komplettes Umdenken der Weg? Wenn Zeit, wie behauptet, Geld ist, Geld also einfach nur ein anderer “Aggregatszustand” der Zeit ist, wäre es dann nicht sinnvoll, auf mehr Geld zu verzichten, um mehr Zeit zu haben?

    Heinrich Böll verfasste zum “Tag der Arbeit” am 1. Mai 1963 die “Anekdote zur Senkung der Arbeitsmoral”, eine Parabel, deren Sinn eine Überlegung wert ist: Ein Tourist weckt in einem Hafen an der Küste Westeuropas einen in seinem Boot schlafenden Fischer auf, als der Tourist Fotos macht. Nachdem er ihm eine Zigarette geschenkt hat, befragt er ihn zu seinen heutigen Fängen und erfährt, dass dieser bereits fertig gefischt hat und mit seinem Fang zufrieden ist. Der Tourist begreift nicht, wieso der Fischer nicht öfter ausfahren möchte, um finanziell aufzusteigen und ein erfolgreiches Fischfangimperium aufzubauen. Am Gipfel seiner Karriere angekommen, könne er sich dann zur Ruhe setzen und in Ruhe im Hafen dösen. Der Fischer erwidert, dass er das auch jetzt schon könne. Der Tourist begreift, dass nicht nur mehr arbeiten zum Glück führen kann. Der Fischer findet, dass er an dem jetzigen Tag einen guten Fang gemacht hat und dieser für die nächsten Tage völlig ausreicht.

  • ko 스트랫 6번줄 떨림과 인토네이션 문제

  • 이 기타를 2016년부터 쓰고 있습니다. 처음 조립했을 때부터 6번줄 인토네이션 문제가 있었습니다. 픽업 높이를 낮추는 것 만으로는 해결이 되지 않아서 마분지를 잘라서 넥심을 만들어서 사용했습니다.

    http://slowbean.net/thread/change-the-angle-of-a-neck-with-stewmac-neck-shims/

    5,60년대 스트랫을 분해한 사진을 보니 넥포켓에 심(shim)을 넣은게 보이더라구요. 그렇게 따라해보니 넥픽업과 줄 사이 간격을 적당히 만들 수 있고, 브리지 픽업에서는 약간 더 간격이 넓어지니까 브리지를 붙이건 띄우건 세팅하기에 유리했습니다.

    그러다가 stwemac 0.25도 짜리를 어제까지 사용했습니다. 종이보다는 좋겠다 싶었는데, 역시 인토네이션 문제를 근본적으로 해결하지는 못했습니다.

    http://slowbean.net/thread/change-the-angle-of-a-neck-with-stewmac-neck-shims/

    넥심이 없는 경우, 두꺼운 종이를 사용하는 경우, stewmac 나무 넥심, 세가지를 비교해보면 서스테인 차이는 없습니다. 생각같아서는 종이 넥심이 부족할 것 같지만 실제로는 그렇지 않았습니다. 물론 초점은 인토네이션이라서 여전히 심이 필요합니다.

     

    풀포켓 넥심은 단차가 없어서 이상적인 아이디어같기는 한데, 넥과 넥포켓 사이에 다른 나무가 보이는 것과, 종이에 비해서 소리가 좋은 것도 아니라서 제일 얇은 부분을 잘라서 그걸 심으로 넣었습니다. 넥을 전체적으로 높이는 것보다 제 기타에는 이 상태가 더 좋네요.

    인토네이션 문제는 아직 그대로입니다. 다른 커스텀샵 스트랫 두대하고 비교해보니 6번줄의 12프렛 이후 떨림은 공통적인 현상이었습니다. 12프렛까지만 잘 맞으면 충분하겠다 싶은데 제가 쓰던 54 커스텀샵 픽업에 비해서 약간 자력이 낮다고 하는 59 빈티지 픽업을 넣어도 그런 면에서 별 차이는 없습니다. 저항값은 비슷한데 두 픽업의 톤이 아주 다르기는 합니다. 54는 쨍하고 59는 부드럽습니다. 

    50년대 스트랫 사진을 꽤 봤는데 당시 픽업이 요즘 픽업에 비해서 5,6번줄 폴피스가 낮은걸 발견했습니다. 줄로 0.5mm 정도를 갈아서 비슷한 높이로 맞추었습니다. 역시 약간의 차이는 있지만 근본적인 해결은 아니었구요. 그래도 톤이 살짝 죽으면서 저출력 알니코 픽업 성향이 들어나니 그건 마음에 듭니다.

    어짜피 전기기타는 픽업과 스트링 사이에 자력이 늘 존재하기 때문에 무조건 픽업 높이를 낮춘다고 해결이 되지는 않는 것 같습니다. 중력과 자력 사이에 적당한 밸런스가 있을 것 같기도 하구요. 뭔가 찾으면 다시 업데이트하겠습니다. 꽤 긴 과정이 될 것 같습니다.

  • ko 안동, 4월에 눈이 내린 아침

  •  

    아침에 창문을 열자 밤새 내린 눈이 쌓여 있었다.

    4월에 눈이 내린것도 수년만이자, 봄꽃위로 하얗게 쌓인 눈은 이채로웠다.

     

     

    회양목도 봄에 내린 눈이 좋기만한듯.

    길가 화단에 노란 꽃도 하얀 눈이불을 덮었다….

    거짓수가 한 열가지 되는 반찬이 다 맛있고 깔끔하고 양이 많다.

     

    정식 메뉴 추천. 반찬이 맛있는데다가 밥도 맛있는 집.

    반찬 나오자마자 맛있어서 사진 찍는 걸 잊었다.  음식 사진은 추후 추가하겠다.

    따로 주차장이 없고 도로가에 알아서 주차해야 한다.

    실내가 넓어 단체도 가능하다.  신발 벗고 들어가는 단체석이 있고, 홀도 따로 있다.

  • en Sprague caps from a movie – on Apple-1 motherboard

  • They tweaked the large sprague caps and the small ones too much for the scene. but it’s still good to see my favorite sprague capacitors on a movie. aren’t they orange back in the days? 

    this board is Apple-1 from this movie Jobs from 2013

    https://www.imdb.com/title/tt2357129/?ref_=fn_al_tt_2

    btw, I wanted to capture the scenes. and it didn’t work with Safari browser. this helped me out. you can capture the screenshot while it’s playing on chrome. it didn’t work while posed.

    the first computer I saw was Apple II at a friend’s place in the early 80’s. didn’t have any interest in it at the time. but the listing on ebay still brings me the memory

    on March 11, 2019

    Before they’ve started to sell those home computers with Win3.0 or Win95 here in Germany, a lot of people owned Apple machines but now they are hard to find here. Not because these computers are rare but rather people just threw them away.

    the caps from the movie have 1080H and 1019H codes on them. they came from 18th and 19th week of 2010.

    I see 7613L on the original Apple-1 board. 13th week of 1976.

     

    they put the fresh sprague caps on the board at ’76

    Did watch the movie with Ashton Kutcher and was totally disappointed. How he has portrayed Jobs was way too much faked. Just my opinion.

    it was on Netflix and didn’t think about the movie that much. I don’t have any interest in someone’s life nor a movie about it.
