6 Slot Neo Geo issues

Hey Guys,

I recently got a 6-slot neo-geo that I put into a cab that had a 4 slot in it before. The 4 slot machine has always worked fine.

The first issue that I am having is that sometime the audio cuts out. Sometimes completely, sometimes in one speaker or the other. It comes and goes.

I raised the power supply voltage so that it reads 5.0 at the jamma harness, but I don't know if there is any other place I should check volts at.

The second issue, is that the board will sometime reset if you switch it to a slot that does not have a game in it.

I have already removed the battery on the board and didn't notice any broken traces around the battery, but I can look again if need be.

Any advise would be a big help.

Thanks,
Brett
