I just picked up a Hill Audio Remix 24x8x16x2 console "as is" (i.e.
broken) for next to nothing. The internal fuses were blown in the
power supply, so I replaced them and the board seems to power up fine.
22 of the 24 channels work and the main buss outputs work. The tape
out and monitor out are dead in the left side. I didn't want to
connect anything I cared about, monitor wise, until had a better
picture of over all health, so I plugged a cheapie set of headphones
in to the headphone jack and left them laying on the console so I
could hear the a test tone while I checked the busses. When I picked
them up a minute or so later, the left earpiece was hot as hell. Not
enough to fry an egg, but about right to heat a dinner roll. I'd like
to covert back to stock headphone use. Any obvious suspects for the
cause/fix?

I've got a Hill Series Three, and there's no such problem.

Maybe there's some kind of electrical short, or you were driving the
headphones to the max?
(that's the only time I heard of headphones overheating)

I suspect that seeing as you were using them as open monitors, maybe you had
the volume turned
up all the way and it was driving the headphones too much?

Try it again with lower volume...

Good luck!

Could also go to the orginal reason the fuses blew. Perhaps driver circuit for
the headphones? Sounds like some AC in there somewhere (bad rectifier).

Don't hurt yourself
