In Reply to: RE: Would You Buy a SET Amp Using DC Heating on the Output Tubes? posted by Tre' on July 21, 2011 at 12:12:41:
DC works well with a choke input supply - that's the important bit. I use a 280mH choke, 30,000uF or so, and then follow that with a Rod Coleman designed filament supply with a gyrator and a current source.
Few if any commercial SET amps would use a choke input, but that's the way to go if you are building and are serious about a clean supply.
