After replacing resistors and capacitors on a late model 60, I get no audio whatsoever. The B+ is over 400V at full line.
I've limited the line voltage such that the voltages at each plate are approximately correct.
The output tube is biased off with ~-2.5V. The top of resistor 47 measures ~-2.6V indicating ~ 10 MA current draw.
What should the voltage be at the top of resistor 47?
Thank you,
Don
