McCormack DNA-1 problems

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.

I also recommend Scott Gramlich of SG Custom Sound.

Maybe the red led needs to be replaced?

2-1 the amp works fine,cheers,Bob

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

Stereo Exchange can fix it. They have a really good service department and they're a dealer. (That's if nothing has changed. I haven't been there in a few years.)

Steve reads these forums pretty regularly. Maybe he will see this and comment.

Is it just the red bulb/led that doesn't light up, but the amp still works or is the whole amplifier dead?
