Mortal Kombat sound issues

[Belike]

Need some help:
I've got a Mortal Kombat 1 pcb yesterday with some sound issues, it has only a continous, disturbing beep and no other sounds.As I can see, there is sound potmeter hacked to one of the connectors, maybe that's the problem.If anybody have the same board, pics would be great.




Thanks in advance!

Yes the pic is from the sound board only, it's connected to the mainboard.

This actually is the right spot for the sound pot, though not very elegantly done. My boardset uses a 47 Ohm or 47 kOhm pot, can't remember which, but it should be stated in the manual I guess.

Operator hacks keep amazing me

I doubt the cause will be the pot.
