Yamaha CR-640 Amp seems to be fuzzy and when I turn the volume up I get crackling in the left side. Not only that but the woofers slowly rise and fall when you raise the volume fast. I want to open it, replace all the little lamps inside (they have since burned out) and generally clean the entire interior. What should I do, what shouldn't I do, and what should I look for when cleaning out my reciever?

    Get some contact cleaner from Rat Shack, it comes in a spray can. I used some on a friend's CR 1040 receiver. The pots were noisy and that did the trick.
    Check here for vintage parts. I got lamps for my Marantz 2226 receiver there.

    Thank you for pointing that out. What else do I need to clean? Like the RCA female plugs, whats a good way to do that? How about other circuitry?
