I checked all the coils I could find, all checked ok. If I put a meter across the grid of the audio tubes ( the small dia pins) I get noise thru the speaker. Voltage across the large dia pins is 2.3 volts. I'm assuming thats filament voltage. These are type 44 tubes. Also across the line ballast I'm getting a output of 83 volts. So 120v on one side of the ballast, 83v coming out. Does that seem low?
