McCormack DNA-1 problems

I have a McCormack DNA-1 amp that has worked perfectly for many years. Recently I turned the power switch on an no red light appeared. I checked the rear fuse and all 4 interior fuses and they are all OK. Does anybody have any ideas what might be the problem? Can anyone suggest a good qualified repair shop in the NY metro area or on the east coast?

Maybe the red led needs to be replaced?

I also recommend Scott Gramlich of SG Custom Sound.

I just upgraded my DNA-1 to the G20+ Ultra. This upgrade is highly recommended. My previous upgrade was in 2014. I went to this present upgrade level because the original circuit board from 1994 had failed. Talking about making lemonade...this last upgrade is a huge jump in sound quality. Included with the upgrade is the Panzerholz isolation base which was reviewed in "the Audio Beatnik". If interested you should contact SMC Audio. Pat/SMC Audio South did a fabulous job on my amp! The sound gives me the best of tubes and solid-state characteristics.
