Sweet Linda came home today.

Well, it seems to be working again. Looking at the schematic, I started with Q7 and all the voltages were unstable. I pulled it and tested it. All seemed good. Powered up and found I had no wild voltages. I noticed the bias transistors were dissimilar so I replaced them with 2n5088s. Put Q7 back in, powered up and....it works. The issue I have now is bias voltage can't be adjusted below 500 millivolts either channel. Do I need to go to a 10K trim pot?
 
Change D6 to a Bat 41 diode and it will bring your bias into the correct range with plenty of adjustment
 
Lower forward voltage. I had your bias problem and Joe suggested changing D6 to the bat41 and it worked perfectly. My bias pot is in the middle now
 
I think I made a mistake. Seems I ordered Nichicon VP non-polar electrolytics to recap the control board instead of FG caps.
Is this going to cause issues? Caps are cheap enough, I can reorder if there is a big issue here.
 
I would expect ANY fresh cap is going to sound better than the best 50-year-old cap.
 
You should change C6 to 470uf and put back to back diodes across it 1n4148

Well, I ordered the 470uf caps and the 1N4148 diodes. I started reading through the tips and archives. Discovered people are recommending getting the 470uf cap in 50 or 100v rating. I ordered 10v because the drawing shows C6 rated 100uf, 6.3v. Do I need to reorder?
