cool thanks!!
:thu:

I plan to dime it and use the preamp output knob as my master volume so scratchy pots wouldn't be an issue for me.

 

Take it apart and clean them anyway. Scratchy pots can also create open spots on the control, or have the sound cut in and out. In some cases, really scratchy pots can lead to signal changes bad enough to blow the outputs or one of your speakers.

 

They're like old TV tuners left on one channel for a cable box. After a while, one setting works, but the rest of the pot is so contaminated, the other positions don't work. Try just turning the pots back and forth with the power off. Sometimes that cleans them up just doing that.
