Thank you Ben for the detailed info - I really appreciate it! Here are my measurements for the reference points you listed:
Junction between C369 and L369: 12.04V
L343 (any side is fine for just sinple voltage measurements): -11.98V
Junction between VR339 and R339: -6.44V
Junction between R311 and R312: 0.897V
Base of Q424: 8.94V
Base of Q324: 9.7V
Base of Q474 and Q347: 11.86V and 10.68V (I assume it's Q374? Can't seem to find Q347)
Emitter of Q414 and Q314: 0.174V and 0.192V
I hope this helps to some extent. Also like I mentioned in another reply, the pot for the A & B VAR knob has been cleaned and it seems to work fine but the UNCAL light stays on no matter how I adjust the knob.
