Quoted from BrewersArcade:Continuing on with repairs to my BTTF. During sound test, the right speaker is much quieter and sounds thinner than the left speaker and subwoofer. Wiring to the right speaker is intact/untouched and its the original Data East speaker. Could the sound board need a cap kit? I've reseated the connectors on the soundboard and reseated the socketed chips with no change. Anyone else had a similar issue?
I have a similar situation. Once in a while, one of the speaker panel speakers (usually the right side and usually occurs when the machine is first turned on) will be much quieter than the other. I find that if I touch the volume potentiometer with my fingers that the sound comes back. There seems to be a bit of static noise but then it comes back.... much like touching a radio antenna when losing the signal. Not sure if its a board issue, grounding issue, potentiometer issue, or what???
