McCormack DNA-1 problems

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

718-224-5083

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.

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.
