RE: WANTED: Futterman H3 OTL project - Harvard Electronics or Tech Instruments

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.
