OK thanks very much. I got the amp with the pots already gone, only the pins from them are left. However, I think you are correct in that all of the information I need is printed on the amps PCB. Underneath where the "gain" pot would be is printed "B50KX2", and underneath the "bass boost" pot is printed "C2K5X2".
I cant figure out what the first letter means, but I think I know what the rest means. So I believe the first pot would be a 50k ohm pot, and the second would be a 2500 ohm pot. I believe X2 means that it is a 6 pin pot as opposed to a 3 pin.
Thanks!
