SYMPTOM: No sound. Amp crackles at power up, and volume pot works. I therefore figure these parts are okay.

SOLUTION: I first thought I had a dead Z80, but a new one did not change anything. I decided to pull some ROMS from the sound section. While removing ROM #8, I sometimes got random sound effects to occur in the demo and in game. I burned two new EPROMS for both chips in the sound section. No change. I then thought this smelled a bit of bad memory in the sound section. I pulled a RAM chip from a parts SNK board of the same vintage, and piggy backed it onto the existing chip. Full sound and music restored! Ten minutes later with my soldering iron and I had a permanent fix.
