Midway PCB Sound Board Test/Repair Tips

If you have a mk1, mk2, nba jam, or any other midway arcade pcb that wont play sound I recommend trying to find a slightly older ATX power supply that has the white -5v line on it and connect it up to your harness with just a regular 8oh speaker attached to the speaker – and + and see if you get sound. What Ive found is that with Japanese candy cabs they just dont put out the -5v needed to power the sound boards on midway games and although the neo-geo cabs will sometimes allow you to hear sound (as long as you have the -5v line wired up) in general the speakers arent directly wired for mono sound and you will most likely get no sound as well. Give this a try with the ATX power supply and see if its your board that has the problem or your cab.
