[Boatanchors] NC-109 Help Needed

Hello, all. I just picked up a National NC-109. It was sold to me as a
basket case but it actually does not look too bad. It should be a fun
project.

1.  Does anyone have a voltage chart? The manual I downloaded from BAMA does
not have one.

2.  Does anyone have a legible schematic. The BAMA one is tough to read.
Surprisingly, Sams does not list a service packet for this set.

3. My problem appears to be in the audio section. The voltages coming out of
the power supply are good. However, there is no audio and no response when I
stick a soldering iron on the volume control. The output transformer tests
good.  Does anyone know what the voltages should be on the audio output
(6AQ5) and the AF amp (12AT7)?

As always, thank you in advance.

Joe Connor
