this mite not be the right place for this, i have a yamaha c-70 control preamp. the sound cuts out on the left and right channels, if you wiggle the volume control knob the sound comes back on for awhile. now it wont play at all, was just wondering if it is possible to fix and where i might be able to find the parts. i was told that the volume control is a dual rehostat and the contact go bad. any information would be helpfull.

thanks
clayton
