I have done a pretty thorough visual inspection. Don't see any bad solder at
the speaker terminals. No obvious burn marks or smells. I really don't think
the receiver is worth the effort to fix unless it's something fairly simple,
which it apparently isn't. I am, however, going to go through the boards one
more time with a magnifying glass to see if there's something I missed.

Thanks for your help everyone.

Yes, I swapped speakers. I also moved the set over to the B speaker
terminals. Guess what? Same problem.

Then it's time to start trouble shooting. No particular "common part" is
the cause of that problem. Any switch on the front of that unit can have
dirty contacts and cause static. Be sure to try them all to see if they
have
an effect, including the tone controls. They all have seperate contacts
for
each channel. If it's not the switches, then I would check the board for
any
bad solder joints. After that, it requires basic troubleshooting skills, a
few basic pieces of test gear, and some basic electronic skills. By the
way,
what does this static sound like? Is it like a hiss, or is it a frying
sound? A frying sound tend to point one toward a bad transistor(s) in the
output stage. Maybe you could explain the sound a little better.

Have you swapped the speakers?

Yes, I do have sound in the bad channel. I think the best way to
describe
it
is that it sounds like a radio station that's not tuned in properly.
It's
staticy and garbled.

I was just reading the post about the marantz receiver static
problem.
Mine's slightly different, in that it goes away when I turn the
balance
all
the way left, and my headphones work fine. I cleaned every
conceivable
contact and circuit and still have the static. The receiver's 32
years
old
so I am suspecting something has died or fried along the way.
anyone
have
any ideas?


Lot's of possibilities. Dirty or worn speaker switch contacts,
bad
relay
(if the old amp uses one) contacts, dried up caps, leaky
transistors.
Headphones require very little power to produce sound, so some
problems
in
the output stage might not show up when using them. By the way,
do
you
have
sound through the bad channel along with the static, or just
static?
