Don't replace it. The static and balance problem you are having is
most likely dirty potentiometers. Go to Radio Shack and purchase
an aerosol can of contact cleaner. Open the case of the stereo and
with the unit unplugged spray into the cracks and holes of the various
pots. Turn them back and forth while spraying.

Does it still sound like contact cleaner would help?

Yes. Go buy it immediately and report back with your results. Keep in mind
that these controls often need to be FLOODED with the stuff to get all the
dust out. When you're done, you will walk away for 10 minutes to be sure the
cleaner has evaporated. Then, you'll try the stereo.
Well, some controls, usually cheaper ones, will actually deteriorate inside,
and if that's the case, the cleaner spray will do nothing. For dust, using
not enough spray will sometimes just relocate the dust. Keep in mind that
most people NEVER open up stereos (or computers) to vacuum out the dust.
Chuckle. Dust or anything else. Most of my stereo/TV equipment came out of
the dumpsters at the apartments I used to live at, and the rest came from
garage sales or ebay. The dumpster stuff usually got peed in by a cat or a
drunk, and blasting the motherboard with contact cleaner brought it right
back. Sometimes I had to replace fuses that gave their lives protecting the
unit from dead shorts. I even made some money selling a few salvaged
receivers at my sister's garage sale a couple years ago. I doubt I have more
than 200 bucks in the 2 complete stereo setups I currently have, including
some nice speakers.
Don't forget, for most people, electronics is PFM, and it would never occur
to them to open the cases. I'm no engineer or electronics expert, but I am
willing to degunk and fix trivial/cheap stuff. I wouldn't pay a bench fee,
but for a nice piece, I'll spend an hour or two putzing around before I give
I just did that with a Panasonic cordless phone whose keypad stopped
working. It made absolutely NO sense. Most Panasonic stuff's pretty well
made, and this phone was never mistreated. I opened it up and found a layer
of something like bacon grease between the soft pushbutton pad and the
circuit board, which contained the pressure sensitive dots. WTF? The phone
lived nowhere near the kitchen. I cleaned the bejeezus out of it with
isopropyl alcohol and it's a new phone all over again.
