when i adjust the volume in my ghostbusters cabinet, i get a 'scratchy' sound.. its not the pcb as it is a 48-1 and it never made this sound in my other cabinet. and any other pcb that i put into the ghostbusters cab, the same sound occurs when adjusting the volume.

do i just need a new pot, or clean the two pieces that make contact?

if i need a new pot, is there a certain rating for one?
 
With the game turned off, turn the pot back and forth from one end to the other 10-15 times. If that dont fix it up, get some tuner cleaner and spray that on it and try again, or just pick up a 5K pot and replace it. there only a few bucks.
 
thanks.. i tried the 15x back and forth and it got rid of the scratchy sound.. the problem now is that it only gives sound from 1/2 way to full volume.. i will get a new pot, but this one said 50 ohm

50 ohms is nothing. It's most likely 50K ohms.
