RE: Tuner Issues; Right Channel keeps cutting in and out, repair possible?

Could be a "tape monitor" switch, since those are in the signal path. Try cycling those (if there's more than one) a bunch of times. Or hit them with some tuner spray or contact cleaner.

Rarely, there can be a cold solder joint or unsoldered connection, or sketchy connector contact in a cable harness link that causes this kind of problem. It can be frustrating to troubleshoot because merely touching the component or connection, or applying a test signal, will temporarily fix it.

Components that fail generally stay failed. Capacitors become resistors, resistors become insulators after releasing smoke, transistors become noise generators or short circuits.
