Respect!!! It was a beautiful crafted masterpiece.Made a new tube amp, 6J5 +27 +45.
cnc winding machine manually wound output transformer. 10mm thick aluminum diamond plate milling machine as a tube amp.
go on look!
100 years ago, the Americans are very great, can create such a good tube out.
你有卖吗?我有興趣
Yes...I use caps with about 2 time more voltage limits /and also brands make caps with more limit that is shown/ and I don't use my amps to work all the time on full power that input signal will go direct and cathodes AC are max., I think You don't like this mode also.
Good and cool listening this amazing tube!
You are quite right. Usually do not enter such a high level. I think it needs to be so high capacitor voltage margin.
2 times the negative cathode DC is definitely impossible. At least I think that would be enough.
Beautiful job - I like your use of a thick piece of Al for the chassis. The finished amp is gorgeous, especially with the globe shaped tubes!

You can also do so one out, texture, and very pretty. It is important that the surface treatment of the aluminum plate. If you are willing to do so, there are difficulties, you can contact me.

That is a very good looking and well built amplifier. I wish I could take a listen to it, you don't usually see such a tube combination. Will you be taking measurements and sharing them? I am really curious how an amp using tubes from 80-100 years ago measures.
Oh! You are very welcome to listen. But you and I apart thousands of miles away ah. If you really want to hear. Always welcome to come to China, I will warm hospitality. Can not underestimate these centuries old goods, but it is far from any offspring tube unmatched.
The measurement data of the machine as follows:
-1db 15Hz-46kHz
Ringing frequency: 120kHz
Distortion: 6% 2w (estimated)
Output transformer parameters:
Primary Inductance: 25H
Leakage inductance: 21mH
Impedance: 4600:8:4
Primary: 2900 turns
All transformers are my own wound.
What argument can also feel free to ask me.
Fortunately, there is the DIY CNC winding machine.
Test instrumentation is: oscilloscopes, signal generators, millivoltmeter.

My main difficulty is my lack of a Bridgeport (milling machine). I'm hoping to get my paws on that missing piece of equipment at some point in the not TOO terribly distant future, though.
