I am working on a bally playboy machine and can not fix the sound, I already replaced all but one capacitors on the solid state sound module, are there any other parts I should look at on here? I do year static when i am adjusting the volume and both pots tested good with a multimeter.
 
Have you replaced the connectors to the board?

Connectors were my biggest problem getting my Space Invaders pinball working again.

PM sent regarding this board
 
there's an ic on there also I believe that's not available anymore, so if that's broken then you have to buy another used and working board..
did you test the speakers ? and sound volume pot inside cabinet ?
