Got a Sharper Image background sound generator for sleeping. Problem is
the 60 Hz hum. Sounds good off the batteries, but the wall wart sucks.
It's sealed, potted probably. Need a good, filtered,small and not ugly
replacement. Less than 10 bucks and it's bought. Otherwise, I'll have to
tear the sound generator apart, but I'm afraid once the 60 Hz is inside
the case, I'll not be able to eliminate it. Any suggestions as to a good
wall wart? oops, 6 volt DC, 300 mA.

Could try wrapping the feed through a toroid?
