Pat, I promise to check this morning and get back to you.
Ok it took to 1:20 PM.
The readings are purely out of whack on T3, T7, T8, T9, T13, T22, B3, B6 and the left RCA jack.
1) Quickly, the RCA jacks should "see" the 100k pot regardless of the pot setting. It should read about 100k ohms. Since the left doesn't, lift the wire going from the wiper of the input volume control to pin 2 or pin 7 of the 12AT7 and see what the pot reads. (I'm not tracing this because you can easily find the left input RCA jack and the wiper of the pot, center lug.)
2) Terminal 3 should be grounded, it is screwed to the chassis plate. Recheck that. I can't imagine why it reads 2.8M ohms.
3) Terminal 7 has a 3k ohm 5W resistor to ground at, again, Terminal 3. If Terminal three isn't grounded it will read odd. Check from Terminal 7 to terminal 3, not the chassis. You should read the 3k resistor.
4) Again, like Terminal 3, Terminal 8 is screwed to the chassis. It should be grounded. (this now makes me wonder where you clipped your meter's ground terminal to when reading.) This might have given you odd readings depending on where you clipped the meter lead. See 2) above.
5) Terminal 9 is a repeat of Terminal 7. Measure from Terminal 9 to Terminal 3, not the chassis plate. You should read the 3k ohm resistor. See 3) above.
6) Terminal 13 is probably Ok. It says climbing to 270k ohms. This is the "Bleeder" resistor for the power supply to keep us from hurting ourselves if we touch a charged capacitor. But the capacitor from Terminal 12 to Terminal 13 will make reading it hard.
7) Terminal 22, like Terminals 3 and 8, is screwed to the chassis. This is the third one and reading the manual it says, "attach the negative lead... of a volt-ohm meter to ground," which leaves it open where to ground the meter. It might be that a ground wire jumper has been left off. Be certain that the IEC connector is grounded to the chassis ground lug and to Terminal 16.
And finally, B3 and B6 are connected to the cathodes of the output tube through the resistors mentioned above in 3) and 5). If it reads high maybe the wire from B3 or B5 to Terminal 3 is not continuous (cold solder joint). Or the problem in 2) above is the cause.
Hope this helps.
