At my wits end. Have a Bally supersonic 2518-32 sound board. No sound whatsoever. Speaker works and wiring to speaker good. Recapped board, new transistors and amp chip. All pins resoldered, and plug harnesses pin replaced.
Please help. Where to go next.

I assume you have tried in Test mode, after pushing the coin door internal button, four times.

Also, when rotating the Volume control, can you hear scratches in your speaker? Anything?
Have you tried playing with the two other adjustables resistors? Place them in the middle position to be safe.

Next step would be to verify the voltages on the board and on the connector. For that you will need a manual with schematics.
