OK, I've done alot of work, and I've referenced many threads and resources. here is where I'm at.
Spot Killer on, Players 1 and 2 leds flashing.
Monitor cap kit, LV2000, frame transistors replaced. I have not connected the HV cage yet, only the main boards, all other boards connected.
No ripple in the PS all test point voltages on the AR board seem good except the 36VAC is low, but all DC voltages are good. I did replace the 3055 for 5 volts to get the 5 volts back up.
6.8V on the main board is around 4.8, all other test points are good.
I found some cold solder joints connecting the main board with the AUX board. Fixed that, now it appears to play blind with the Spot killer on and static in the speaker.
X and Y out don't have ripple and are relatively low. DAC's at A10 and F10 have good signals.
I have limped this to the point of playing blind but I don't want to plug in the HV cage until I can isolate the spot killer. Any other tips, or places to check?
