Quote:A side question, should I be getting a voltage at the yellow/green tracer wire out of the power transformer? I am not currently, but was wondering if I should be. There is none listed on the voltages chart in the service bulletin. I am trying to figure where the power for the 2nd DET. AVC tube comes from, as it appears absent, as indicated above.

The yellow/green tracer wire is the B-. It's the most negative point in the radio. You can measure a negative voltage between it and the chassis. The 2nd detecter gets it's "power" from the radio signal itself. It is a diode (actually connected as a double diode) and conducts on the positve swings of the signal only enabling detection.
