The amp still powers on. I assume the amp circuitry and power supply is fine but I don't really know. I didn't think of wiring up the high-level inputs to test. I'll do that today.

I assume I'd need an electronics repair shop to replace the connectors. Would likely involve soldering on a new RCA jack. I don't need the XLR input if the RCA is working as my receiver doesn't output XLR.

Thanks for the suggestion to test.

Anyone know a good repair shop in Calgary?
