What are your impressions over time? Have you checked the quality of the output transformers? What inductance? I ordered one for myself. Your video inspired me. Thank you, I will watch and do it.
Sound quality is good, but mine has gotten 5u4g arcing. I guess the culprit are the capacitors next to it, so I tried different values and swapped to a new tube, but this second tube started to arc a few days ago. Not very fun 😭 but it could be different for you. Good luck!!
@@Tinker_Box Specialists in tube amplifiers suggested that the first 150 uF capacitor was to blame for the breakdown of the kenotron. It should be reduced to 30-50 µF. And increase the second to 330-470 µF.
@@manashara2504 That was what I tried, although I went through different capacitor values combination. I’m not sure what my final values were but I’ll check it tomorrow and let you know..
@@manashara2504 I used two 33uFs in parallel for the primary, and left 150uF as it was for the secondary. Once my new 5U4C tube arrives, I plan to take off one of the two 33uFs, and see how it goes.
Did you happen to measure the diameter of the primary winding wire of the output transformer? Approximately by eye? What are the dimensions of transformer iron?
Nice work. I like the design. I feel that point to point wiring is better and provides a better sonic than PCBs.
Well done🎉🎉🎉
Amplifier valvulado são ótimos!
well done.. looks Great 👍.
Very good job. Point to point wiring is fun
🙂 thanks!
Este kit donde se puede adquirir????

전압 측정치에 대하여 질문드립니다. 회로도에는 6J8P 6번 핀에 +85V가 나오는 것으로 되어 있는데, 실측치는 15V 정도 입니다. 나머지는 전압은 회로도와 유사한 값이고 소리도 그런대로 괜찮습니다. 어디에 이상이 있는 것일까요?
글쎄요, 말씀만 듣고 답을 떠올리기가 쉽지 않네요 ㅠㅠ

I didn't get in to that, so I can't say about the wires inside. The dimensions are 69mm(w) x 58(l) x 58(h). Have fun!
i cant find the schematic on your link only the layout
@@rduwe9466 oh, I’m sorry. I didn’t know that until now.
Those tubes are on the piss.
eek! i just ordered one of these. your wiring is very bad. no need for all that copper. why are you using tape?
Show schematic. What tubes are you using ?
