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?

Or contact stevemcx here on Audiogon. That's Steve McCormack
Hi Paul

In the NY Metro area I've had Scott Gramlich of SG Custom Sound do a lot of repairs for me. He is out in Douglaston Queens NY. Near the LIRR.

Here is his info:

40-33 235th Street
Douglaston, NY 11363

2-1 the amp works fine,cheers,Bob
Maybe the red led needs to be replaced?
I also recommend Scott Gramlich of SG Custom Sound.
