I can't find a schematic for this game... I got a issue with the sound... it keeps turning the volume up to max even when the wires are disconnected from the switches and jamma haress... has anyone seen this issue before?

Or if anyone has a link to a PDF schematic that would be wonderful!
 
i know this a really old thread but bump same question
