Now I've got a whole bunch of horrible 60 Hz hum in the audio.

The moral of the story: unplug wires, instead of cutting, and if there is no plug unsolder the wire and add one....If you can't reach the solder joints it probably means the makers wanted the stuff on both ends to be removed as a pair, or your missing something important.

I'm guessing it was an audio cable you cut? Try to see circuit wise what is on both ends and how it connects. Perhaps it can be replaced easily with some modern cable you have on hand.
