Have a Fischer RS-1022. One of the channels is blown. Main fuse okay. The two speaker fuses on the exterior of the unit are okay as well. Is this pretty much junk, or is there an easy thing or two that I could look at and check?
Unless I miss my guess, that is a Pacific Rim unit using package amplifier modules. With a little bit of testing, that makes the answer to both questions "yes", as the unit is pretty much junk, but those modules are easy to replace if you can find them... and they are available. Take the part-number off the bad one and search for it.
But, before you go ordering parts willy-nilly make sure that it is the amp and that it is actually blown. Look for internal fuses that may be blown, and verify that the front-end and pre-amp sections are good. If that is the case, it is very most likely one of these package amps.

The FISHER is about twenty-five years old.
I plugged in a pair of headphones into the front headphone jack. Same thing -- blown channel. Is that telling us anything?
As far as internal fuses go, are these the fuses I'm thinking of, the glass tubes with a filament inside, or do they look different? Took off the hood and I'm not seeing any fuses.
Also, the balance only works at the extreme. Turn it all the way to the left and you get sound. Turn it just a hair and crackle, the signal drops away. Don't know if that's the result of a blown channel versus perhaps it's something to do with a balance.
On those receivers, the headphone jack is driven from the amps, there is no separate headphone driver. You may have a problem no worse than dirty switches or controls, so I would start there _before_ looking for anything else. Obtain a good-quality contact cleaner (non-residue) and a good quality low-residue control/tuner cleaner. Clean with the one first, then the other to 'finish'.
Yes, if there are internal fuses, they will be the small glass ones you will recognize. They may be somewhat smaller than the common "1/4- inch" fuses, but they will be obvious for what they are.
And if the balance control is wonkey, that would explain the blown channel. Again, try cleaning, look for a detached wire/cold-solder... try waggling the wires a little (VERY CAREFULLY) and see if that helps.

Look for picofuses or fusible resistors, especially if your amp uses those black STKxxxx amplifier modules.

Fuses on this vintage type stereo if that's what it is I didn't see the previous post are usually on the back panel their 2amp or so a lot of times I would clean all controls with contact cleaner especially if it has a tape monitor switch.
