RE: There is an easier way to do this.

There is lots of bias voltage available. I can easily crank it to -15 but when I do, the current measured on a through the meter ammeter (digital) is in the 20ma neighborhood and that is for the PAIR of tubes. When the bias pot is all the way CCW (looking down on it) the neg voltage is around -11 and the current across the 18 0hm resistor is barely 35ma. This is direct reading, not interpolated. The tubes are not cherry-ing and the total current draw is 120W. I have seen that current go higher when output tubes are running hot (on other amps, never this one). I grant that setting the balance pot to get equal voltages through all the network of resistors at the grids of the two tubes is not "by the book" so yes I guess I need to cobble together a giant resistor for the output load and pull the phase splitter and hook up my scope. Was trying to avoid all that.
I have used the weber calculator before on other devices but lost link so thank you for that and I will report back. --Tom H
