I finally got time to work on the 620 this morning. I put all new wires to the tone control, and also replaced all the speaker wires. The radio only works with the tone control in one position. If I switch to the open or .003mf circuit, I get nothing. Plate voltage for the 42 tube is 10 volts (if I am using the correct method to check it). When the radio is working, volume is about 1/2 of what it should be. The 42 tube tests very strong. Something is very wrong. Any ideas?
