Seeking Repair for Bose 1801 (Tallahassee to Atlanta)

I don't recommend any repair shops in your area which I'd put as somewhere around Albany. I grew up in Leesburg, home of Luke Bryan and Phillip Phillips but I never heard of them before I moved to Michigan 20 years ago.

Usually you trace signal path from driving section down to the output with either oscilloscope or headphones with split wires

Thanks for the recommendation for diyaudio. I’ve done some basic tests and it’s definitely related to the input jacks and possibly the hot power wire. But messing around inside that amp scares me 😂. 

Good amp, but I don't have a repair shop suggestion for your area. Doesn't sound too serious, maybe a bad input cable? Remove both inputs to the amp and see if still hums, It's definitely not an output device, more likely input cable or capacitor. Might want to check or post on diyaudio.com.

Wow an 1801. I have not seen one of those since the debut of the amp at an L.A. audio show. I'm not sure I would put any money into repairing an amp that old. I doubt the output devices are available anymore. Blow one component that is obsolete and you have a boat anchor. I'd just buy a new amp or a used amp that is not as old.
