Subject: Re: power supply buildings for 4 tubes modules

I'm not planning back to back transformers or hammond (probably
370adx), i am just thinking about how i gonna build the power
supply,and these are the two ways possible i found. But i need your
advices i'm still a student in electronic...
I was thinking about one power supply for it all... and you are right
when you are telling me to think about adding more modules in a
future, but i'll built another power supply for my next 5 modules i
got a lot of 50's computering schematics to transform to audio
modules, and i'd like also to make tube ADSR modules so if any one
have schematics, but for now i'm still working on the power supply...
