Your best option is to send it to SMc Audio for repair. And it would be silly not to have it upgraded while it's there. Pat and Steve turn out some of the best sounding SS amps you're likely to ever hear. This is a perfect opportunity for you.
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.

+1 @ozzy62 ----- I followed along with a few folks who checked into this with Pat/Steve, and we concluded sending it in and having the nice rebuild sure makes for a nice alternative while it lasts. And, you can end up with a really nice amp for the $, compared to buying and all-new amp, if you are open to it. I just did something similar with one of my own other brand SS amps. It sure sounds nice, totally worth it, fwiw. Maybe worth a few phone calls to gain confidence going this route. |
This may be a very simple fix. I have the same amp. Take off the screws on the top of the amp. Inside are 4 rail fuses 2 on each side. If any of those fuses are blown the red light will not go out. Check or replace those fuses and you will be back in business. Shouldn't take more than 30 minutes ad it may save you some aggravation. I was back in business for $6.00 |
@mike_in_md OP said he already checked the fuses. |
