In Reply to: Maybe the problem is my first filter caps. posted by DAK on January 13, 2017 at 10:58:35:
"The wiper is 50k 1/2w cc connected to the power tube grid stopper"Did you mean the wiper of the pot connects to the bottom of the grid resistor?
BTW I think you said there is -60 volts feeding the pots?
two 50k ohm pots in parallel to ground is a 25k ohm load.
60/25000=2.4ma. of current. That should be the total load current on the bias supply as long as the output tubes are never driven to grid current (overload).
