mono sound is good enough and you can run this song through two amps. I still recommend you to have at least one tweed amp with well broken speaker and the tubes.

오랫만에 참았던 이베이 나들이를 하다가 눈에 들어왔습니다. 판매자는 12ax7이라고 합니다만 이런 관은 처음 봅니다.
I dropped by a friend’s place to pick up my big red bum fuzz and hang around. then I dug this EH germanium OD out of a big plastic box.
I’m not sure what this NTK275 exactly is. but the same one shows up on ebay. and I guess it came from 60’s or 70’s
It’s the pile I dug out my bum fuzz and this germanium OD. I know few more guys with the same symptom. falling in love with fuzz pedals. don’t worry. some of them have wives or girlfriends. not all of them of course.

5r4 365v
5u4 373v
5v4g 384v
it seems the nature of this tube. I’ve been using a few Bendix 5y3gt with Fender tweed amps. and it’s my first try with their 6v6gt.
Researchers at the Massachusetts Institute of Technology (MIT) and Harvard Medical School have teamed to develop a novel tattoo ink that can show your body’s health changes.
The novel ink consists of biosensors that react to changes in the tissue fluid and make the skin an “interactive display”. So far, researchers have investigated four biosensors that respond to three types of body information, changing their colors.
As the pH-value increases, the color changes from violet to pink, an increasing sodium content is seen as a bright green under UV light, and blue becomes brown when the glucose level increases.
This animation from a video of the researchers shows how such a tattoo might look like: 
Especially for diabetics, a tattoo with ink that reacts to an altered glucose level could be useful. They have to prick their finger with a small needle if they want to measure their blood sugar level – usually several times a day. This procedure can be painful in the long run and can lead to small scars.

[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
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.
had a chance to check out the chassis. Blackface and Silverface amps are far from my taste but people around me have lots of them. and I’m getting into them.
