unclej Posted June 29, 2006 Report Share Posted June 29, 2006 ok, i hate to be a thread hog and i'm getting to where i hate to ask for help but this carvin has got me stumped. i don't know what model it is but it's a tube amp on a pc board. it has a rhythm volume with a push/pull 1meg pot controling volume and bright. then it has the same type of pot that says master/boost. next is lead drive/on and lastly master/high lead. two of the pots were bad and after replacing them i get sound out of both channels but i'm getting a very high pitched squeal not. the volume control will raise and lower the volume of the squeal. it doesn't over power the sound of a guitar..it's more like it's in the background. one lead from each of the pots terminates into a small value resistor..is one of those the likely reason for this squeal? thanks john Quote Link to comment Share on other sites More sharing options...
