Need help with a Gyruss PCB

[PaulSwan]

They would usually be the same - hot as in burning hot?

I'd suggest that you download the manual/schematics and then if you have a multimeter you can check the amp's power and connectivity. I can't remember if this PCB has a strapping option for stereo to mono for normal cabs, or if the bootleg has this arranged differently from the original PCB.

Yes, hot like in - burning.

I already had the schematics and the amps are getting power (my father has looked at it with a multimeter a while ago).
Well, i appreciate your help but i think i can't do any more.
I have no technical background to dig further in the schematics.
Maybe i have to look for a replacement of the soundboard.

Beware of the edge connector pins, looks like in very bad condition.
