I use to have some stones like that but I wouldn't know where to begin looking for them.

Mike if you are pooped... stop.....and there is tomorrow
I'm here ... had stuff to do.... I'm a little concerned on 2508 #2 about the 5 volt imbalance between +/- 65... has this board had the full metal film resistor conversion ?
2508 #2
Will you verify the following:
TR-05 emitter
TR-10 collector
ZD-01 V drop
I want to see if the imbalance is on the board or getting lost externally
The critical values are the voltage dividers...
R-01/02/08/09/25/26/27/30/31/32 these control ( kinda ) the reference levels for the transistors to do their thang!
Wait a sec... where are you measuring the - 65 on the 2512 ?

Here RIGHT ??
That's the other end of the same trace......
So if the emitter/ collector are putting out the correct voltage...
Its that resistor R-16 or the pin ( female / male ) , cold solder joint / pin to 2512 or a stressed trace....
OR
You have the same goo on the female pin of #2508 #2
