RE: Biasing a 300B amp - by ear?







Vinnie,

No, my big "Triode Music Amp" or a "Lab" amp I built with Mr. Fulton's input in 1985-1987, six chassis, 500 pounds, P-P-P 6B4Gs. It had nine regulated DC filament supplies on each channel, and I had 20 turn adjustment pots, and a Fluke 8060 A to measure it all. I was also 21 years younger and could hear 2/1000ts of a volt...but barely!! Seemed to be repeatable way back then - when I tested myself.

Jeff Medwin ( Vinnie, its the bottom six chassis, amp was awesome.)
