From a guy named "Dan M" on youtube:
"""I had a very similar problem (loud buzzing/ humming sound when turned on). Ending up replacing 4-5 of the larger
electrolytic capacitors that had gone bad and it worked fine afterwards.
I believe it was the largest 4 or so caps, not including the very
largest. Need soldering experience to replace the old ones. It also help to have an
in-circuit (not all are) capacitor ESR meter to double check
which ones are bad, without having to remove them first.
Read elsewhere this is a common problem with the older wave radios because of a design flaw. They never turn off! The power button drops volume to zero, but circuits otherwise are constantly on, meaning they stay warm all the time and the caps dry out faster."""
Not sure if that's exactly the solution to the problem, but of all things, replacing big electrolytic caps is the easiest. Also, I'm pretty sure these are going to be shitty (read cheap) caps, so it won't be an expensive fix. I had to get the Bose dig in somewhere...
Good luck! Here is the link to the video: https://youtu.be/5I8t7tRO2pc
