Mortal Kombat volume adjust

[Vis3c]

have a little question here 

i just got myself a Mortal Kombat 1 Pcb and put it in my Mortal Kombat 3 Cabinet.
but the volume is very loud. i adjusted the volume with the 50k pot (or what ever its called)
but it only gets louder not quieter.

sorry to bug you guys with my questions

I would remove the pot and measure its resistance from end to wiper. from the little you said i think the pot might be bad.

[Vis3c]

yeah, thats what i tought too.
but can you say which pot i need? 5k, 25k, 50k?

50k
