Hi,
I am spinning in my mind building a Tube Amp in a glass box. I have a glass company so the glass chassis is the least I am worried about. But on the rest I have some doubts:
The question is which transformers should I use? I have read a lot of posts on forums, there is a lot of discussion. I have some experience with several arduino projects and vintage car radios which I have retro modded with new modern technology but this field is new to me.
I am planning to build a Audio Note M2 tube Pre-Amp together with a Audio Note EL84 tube Amp
First question:
For the EL84 Main transformer I need: AC250V 350ma/6,3V 4A. Those are on the market, for the M2 Pre Amp I need: AC 300 - 0 - 300V/ AC13,8V /AC6,3V. Would it be possible to use one Main Amp for both Amps, is this possible, are they on the market and which would you recommend?
Second question:
For the Output push pull transformers it is not clear how this works, I see a huge variety of transformers on the market from 12-30 watts. What is the best to use? Can you use any of them, will the power of the Amp as big as the transformer? I can imagine the Amp is capable of handling a certain max of Watts?
Third question:
The Choke: I have read online that a choke of 20 Henry 200mA should be suitable for the Audio Note EL84. The pre amp uses a 20H 50 mA choke. Is it possible to use one choke for both Amps? I can use a 20H 300 mA version, or am I simplifying thing too much here?
Last question:
The glass box will not connect any of the grounding to the chassis, I assume using a copper rail for this application would be sufficient, agree?
The rest of the project becomes more and more concrete. I hope you'll will be helping a little bit with the above questions. Thanks in advance for your help!
