Certainly there are other causes than the relays, as many, maybe even most, things that can go wrong will only go wrong in one channel at a time. I did buy a radio on eBay that had half volume in one channel, and it was not a relay kind of thing. But the tip-off that it's a relay is the test of turning the volume way up. spinning the tuning dial, unconnecting and reconnecting some RCAs on the back, switching the source, and kBlam -- the missing channel comes back. I'm guessing that enough voltage will burn a hole through the corrosion for a short while.
