So I'm working on restoring a Gauntlet that was converted to a JAMMA fighter. I bought a sound board and rebuilt most of the wiring harnesses and bought a cheap Gauntlet II board off of eBay. It all works great but after a little while it warms up a bit and when the bass-ier sounds hit it starts chirping and eventually begins making an annoying sound like farting.
Like so:
The chips test out OK in the menu test. So I'm not sure where to begin or where to look. Any ideas?

Oh Gez!...
