I've been working on this board for some years now. Worked fine for a long time then stopped. However, I think I've narrowed in on the issue, I just don't know what's causing it. Using a Ray Carlson PSU, the 9v line puts out about 9.5 to 9.6v consistently. This is verified when plugged into the board. However, when I flip the switch the AC voltage at the DIN drops to 6.5v and 5.2v at the rectifier.
I've recapped the entire board, removed and inspected the coil (it's fine so I put it back), removed C20 and C21 (tested fine), Replaced the 7805 (not necessary, but I didn't know that at the time as it was only putting out about 2.5v to the VIC II).
Any ideas on what could be causing this?
