Anyone have any idea why one Pac PCB would produce a hum bar while another runs fine? My understanding of the hum bar issue is that it's likely a connector or fuse issue (ie: cabinet hardware that remains the same between these two boards).

Humbar is usually an a/c issue or power supply. Bad fuse holder/capacitors/connectors/
You know arcadeshop has a pac/mrs pac hum bar repair kit. I wonder what it includes?
