I'm not sure how these receivers work, is there possibly a transformer for left side and one for right side? Maybe something got blown? Unusual that both lefts work fine but neither rights do. Also, there's a couple random buttons that, if you press, the thing starts massively cutting out and getting scratchy. I attribute this to him trying to clean the whole thing out with steel wool Hopefully that can be fixed with some contact cleaner and dust spray.
BTW there are only two amps, A and B run off of the same amp, so you are running
two speakers off of one amp, basically.
Try cleaning the contacts, and a few tranquilizers might help, but my audio store used to sell
proton, and while quite well reviewed the return rate was rather high. Big problem is that if you replace one thing another will break soon after. STUFF just gets old.
