I added a line bypass cap, and there wasn't a noticible difference in the hum, but after the set warmed up a few seconds I got a very very loud hum/buzz, like you get when the filter caps are bad. I think something blew. I pulled the condenser can and don't see any visible damage there. I'm going to step away from it for a couple of days and start from scratch. I think I'll replace the caps in the can again just to eliminate that as a problem and go from there, rechecking all of the wiring in the whole chassis.
