Trying to come up with some culprits for a weak channel on one of these guys. Not sure if it's just weak, weak and distorted, or weak and humming. It's not in my possession.
Output tubes are unknown Chinese models, there's tick #1. A driver socket is worn out (wiggle test), there's tick #2. An electrolytic cap's wrap is shrinking (can't see the tops to determine bulging on this model) so I'm counting that as tick #3.
Are these known for any specific issues? Other than being 30 years old of course.
*edit* Suppose it would be very pertinent to mention that the level pots are bypassed...
