Thanks Mr Fix.
I was measuring Pin 3 to get my screen voltages. When I measure Pin 4, which on Frank’s is Grid #1, I’m getting -29 dc on the 2 - 42 output tubes and -13 dc on the 42 driver tube. Is that the control voltage you referred too.
The speaker and it’s wiring has not been touched and is original. When i put the probes from Pin 2 onto Pin 3 of the 2 42 output tubes I get a very high reading. Am I doing that correctly.
The radio does work and picks up the local stations but low volume that doesn’t increase with the volume control. The one 42’s output tube’s voltage is very low from the 300 dc that the schematic indicates it should have.
