Thanks for the advice. I did isolate the problem. One
thing I know is the fault of my receiver, though, has
puzzled me for years. When I first turn the stereo on,
both channels crackle.

Probably due to dirty switch or level control contacts.

The crackling quickly subsides.


But when I change the volume, I get more crackling, no
matter how long the stereo's been on. It's not constant,
but flipping the volume knob back and forth makes both
speakers crackle. Any idea what's up with that?

Probably due to dirty level control contacts.

You can buy contact cleaner at most electronics stores. Unplug the unit and
remove the case to shoot the cleaner into the various contacts. Move the
switch knobs as you do this to dislodge any debris.
