Well I contacted Tom Callahan (?) as previously recommend and conducted some test he recommended as the f4 fuse kept burning out. I disconnected j2 and the fuse continued to burn out. In fact I disconnected j1, j2, and j3 at the same time and fuse still burned out. Not sure what the problem is or what test to do next, blew out about 7 fuses, will need to buy more.

Thanks...

The fuse blew and NONE of the connectors were hooked up to the power control board? That is impossible unless someone hacked in a power wire directly to the board or power supply. Or power is going to the cabinet grounding wire braid.

Hello,
If the F4 fuse burns without connectors connected, check and change the rectifier Bridge BR3, and test varistor.
