It is likely that if one of the power caps failed, then the other similar caps (in both units) also are at end of life. Could also be some other tired components - slow degradation of sound can be missed since you constantly adapt to the 'new sound'.
Perhaps you can post a picture of the inside of one of the amps. Could be that these use circuit boards (rather than point to point), which have their advantages and disadvantages.
