Marc	Re: Rectification Tube? AP: Can i use a EZ80, EZ81 with a voltage of 340v? yes Or Can i adapt a 6.3v for a tube like 5u4gb? I believe you could only do this if the filament winding is separate from the rest of the tubes as the DC 'rides' on the filament voltage. I have also a 11.5v can i use this? for the rest of the tubes... The poweramp is 50+50W, which and how many rectification tubes? Two 5U4's should do it nicely. That would give you a decent low impedence power supply. That's a bit beyond my depth tho. Are you building a guitar amp or a stereo? I'd be more inclined to use SS rectification with that much power. Anybody else want to flesh out these answers? Marc
