Need recommendation for repair service in CA bay area - McCormack DNA-1

My DNA-1 powers up but the protection circuit won't turn off so the amp never outputs audio. It has a red led (protection) and a green one (power on). When you power on, they both come on and the red one should go off after 15 seconds or so when the amp is ready to work. The light stays on.

I unplugged input cables and output speaker wires. Same problem. I plugged into a different outlet / circuit. Same problem. I removed the over and didn't see anything obviously burned or loose. Checked all 5 fuses - all good.

So time for repair.

Please let me know of a recommendation in the California SF bay area ideally.

FWIW, I've been investigating the McCormack lines looking for an amp for another system. I suggest you do some research as well. There have been considerable conversations about failures of an input board in the DNA .05 and DNA 1 model amps. I don't know if this could be your problem but if it is you may not want to pursue repairs. One of the posts in a thread is from McCormack describing the problem and why it is in their opinion not 'repairable', at least why they will no longer do so anyway.

Good luck............
