And there was a bad batch of electrolytics from china some years ago;
something about industrial espionage and snatching the recipie for
capacitor goop without knowing it was a bad/rejected recipie... I am
thinking from the 1999-2002 time range.
If it's just the wall wart, it may make more sense to get a new wart
with the same voltage and equal or better amperage. You might wind up
splicing the old cordnon, but you should be fine.

My basic thought was a bad capacitor as this sounds like the typical
hum one would get if trying to operate a car radio that expects DC
with
a cheap transformer providing AC. Don't they normally use
capacitors as
filters?
They do, and electrolytics can dry out. Open it carefully and
replace the
capacitor. Pay attention to voltage rating and polarity as well as
capacitance.
