I've built a few amps but never a fixed bias one. I'm in the process of building a 5f11. I'm confused. I watched Uncle Doug's video about the Vibrolux he went over, and he gave figures on biasing it but never showed how he got those figures. His formula included resistance from the primary tranny windings for each 6v6 (?), voltage drop, plate current, but he never said how or where to put the probes on the meter to get these numbers. I'm gonna start off without the 10K bias pot for now. Can someone tell me where to get these figures for calculating plate dissipation? And the mathematical formulas?
