1st Choice: Seeking Electrical Repair

2nd Choice: For Trade (contact me for my wish list)

3rd Choice: For Sale

Lots of upgrades.

A couple of electrical issues.

Otherwise solid, clean, & mechanically sound.

The cabinet is about an 8/10. Some fading/scratches/nicks. The PF I'd put say 9/10 (but I'll be conservative & say 8/10).

Electrical issues:

1 - Nagging switch matrix issue. U20 on the MPU (now socketed) blows & usually (but not always!), column 4 goes out. Sometimes after a couple of minutes, sometimes after a couple of months, with no discernible pattern or consistent culprit. Troubleshooting has cast suspicion away from the following culprits by disconnecting them, swapping them, inspecting them, etc.: MPU PCB, coin door, The Power mini PF, magnets, all flasher bulbs, actuating coils, Great Lakes opto board, clock. That pretty much leaves wiring (probably in the flashers or switches?) as a culprit. Most wire bundles have been inspected visually & loosened.

2 - Slight audio crackle on some quiet callouts.

3 - Clock PCB opto(s).
