Ok- My voltage check results are as follows- they follow the format of >tube location, type: (result-) pin: should be/is, next result...

For All Tubes: H: 6.3VAC/6VAC

Det. Osc. 6A8G: Osc Plate 150V/135V; P:250V/265V; S:100V/100V

I.F. Amp. 6K7G: P:250V/270V; S:100V/100V

2nd Det.-AVC. 6J5G: P: ?/0 No "P" voltage specified, none showing when tested. According to the specs in my RCA tube guide, it should be between 90V and 250V. The overages on the other tubes add up to about 90-100V, and I will be rechecking my connections for this tube.

1st Audio 6K5G: P: 170V/210V

Output 6F6G(1)(from below, on right): P:250V/265V S:240V/255V

Output 6F6G(2)(from below, on left): P:250V/260V; S:265V/280V

R.F. 6K7G: P:250V/255V; S:100V/100V

Electrolytic #57 connected to both sides: 330V/300V; + and Ground: 315V/280V


Let me know how this sounds...

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.

Thanks!
Scott
