5F6A came with two, maybe slightly more different versions. V2 cathode bypass cap and tone stack are the differences. I’m trying both of the versions

  • en interesting amps and cabinet from John Mergili

  • recently got me a 5F1 champ cabinet for 10″ speaker from this guy. the quality is great indeed. I’ll update with some pics after I finish the amp inside of the tweed cabinet. a friend is playing his tweed champ with 12″ speaker more than the stock 8″. I’m going to start with WGS 10″ ceramic speaker which came with the cabinet.

  • 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 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.

  • 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+ was 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

    then I noticed the vintage amps with the original caps from 50’s and early 60’s are more vulnerable with 5v4g to 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. didn’t have an issue with my 5D3 which has new filter caps either. 

    [EDIT again]
    one of my 5V4G tubes shows very low B+. the 60hz hum came from it I believe

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

    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 jamming with youtube. 5v4g sounds still alive with this stereo and digital setup to me. but, m-track 2×2 is cheap and sharing the one single full bandwidth with usb and instrument at the same time. it sounds good while using only one of them. it sucks when the knob is at the center.

    it’s the knob on m-track 2×2. don’t buy it if you want to use your guitar amps as monitor speakers while playing guitar through the direct input. maybe I’m just doing this wrong.

  • en DNA: Life’s Changelog

  • One of the most interesting things about DNA is that we have discovered, in humans, the 3% of the code which builds our physical bodies also has encoded within the bodies of all of our ancestors. We can switch on these old systems (in animals of course since this would be highly unethical to do to human beings) and give a chicken teeth or scales. We are not just us. We are all the physical forms in our lineage.

    Now, that accounts for 3% of our storage. What of the other 97%? It is memories. Now the skeptic will go “yeah right Mr. Science”. Hear me out here though. Why is it so hard to accept memories encoded into the helix? In fact all “instinct” is encoded memory. What beach to lay your eggs by the light of the full moon if you are a tortoise. Where to migrate if you are a starling or a monarch butterfly. Sharks even have maps of the magnetic markers on the seafloor. None of this is learned. It is there at birth.

    There is a very good evolutionary reason for this. Rapid adaptation. We have a repository of past experiences so we do not have to reinvent the wheel every time our environment changes. Human beings have noted this for at least as long as we have records and this has given rise to theories of reincarnation which appeared in nearly every civilization on Earth. Science has resisted this because it sounds too “supernatural” in the same way they resisted the “Big Bang” because it sounded too much like creation. Yet, it is anything but supernatural. It is entirely natural and the only explanation which makes any sense.

  • en VHT standard 12 – a fat tweed deluxe 5e3 clone

  • it’s getting better with some NOS caps and tubes. 50’s Jensen does something of course. VHT standard 12 is a bit bigger than the original tweed deluxe. and I like this cabinet as well. I might try P15N at some point

  • en Fender – Jensen speaker phase were reversed in 50’s tweed amps

  • I just tried 9V battery trick for 50’s Fender Champ 5F1 and Deluxe 5D3. and the speaker wiring turned out being reversed. both of them still have the factory wiring.

    And, both of them move backward (to the magnets) when they wired 9V + to the white wire, and – pole to the black wire.

    They mostly say there is no absolute speaker phase unless they are in the same cabinet. at the same time, many people say the speaker cones move forward when they hooked up in the right direction with 9V battery.

    Fortunately, 9V battery didn’t kill my 8″ Champ speaker, nor 12″ Deluxe speaker. but I’ve read some cases this trick killed their speakers.

    I’m not sure with 50’s and 60’s Jensen speaker’s correct phase. but, I started to believe Fender hooked them up this way. I’ve seen only 2 cases. and will update if I come across any Jensen speaker with different phase.

  • en 50’s Switchcraft 1/4 black phone plugs

  • this switchcraft black plastic plug looks always nice to me. especially with vintage Jensen speakers and tweed amps.

    I recently noticed the material and the shape has changed through the years. I’m not sure with the exact timeline but, the first and second left ones look a bit older with the different shape of the end tips.

    the first one on the left looks like the oldest brother. it’s the one for my 5D3 with P12Q now.

    the next one came with 1953 tweed deluxe 5C3. the rest of them look like came from 60’s or 70’s production. I’m just guessing. I’m wondering when they started to put the nylon spacer not bakelite.

  • en a friend’s beautiful Les Paul

  • all the black plastic parts have changed with vintage correct white ones. this Joe Bonamassa burst #70 has beautiful top and dark back with ’59 profile neck and Burstbucker #2 and #3. the orignal 50’s burst Les Paul guitars mostly had 7.5k to 8.4k pickups and many of them had hotter ones on the neck position.

    Gibon’s burstbucker was made after the original PAF pickups which had unbalanced bobbins. I’d put #3 on the neck and #2 on the bridge. personally the best PAF replica was Timbucker from Tim white I got at 2003 with my Brazilian freboard 59 historic. and, at the time a few friends on Lespaulforum.com tried Seymour Duncan Custmop Shop PAF replicas and it was a great pleasure to listen them.

    The same Duncan Custom shop PAF pickups are coming for this Les paul. and I believe he’d love them over burstbucker pickups

    more vintage correct parts like truss rod cover and square jack plate are coming as well.
