Amplifier repair in the Baltimore/Washington area

I had a fairly close lightning strike about a week and a half ago that left a couple of my various electronics in different states of partial failure.  (Despite the fact that my amp is behind a surge suppressor.)

My home theater amp, a Sherbourn 5/1500A, now makes a couple really loud popping sounds on startup.  Otherwise, it seems to work fine.  I contacted Emotiva (which bought out Sherbourn), and they said that they don't provide repair services for any of their legacy systems.

Can anyone provide recommendations for a good tech in the Baltimore/Washington area to look over the amp?

Thanks in advance,

Hi Michael,

Protech in Silver Spring has done some work for me, they are also authorized by Mcintosh to do work on their equipment.  I was very satisfied.  Good luck.

Bill Thallman at Music Technology is great.  They are located in NVa just off the beltway.
+1 on both Protech and Music Technology.
I have used them both. You might find yourself having to be patient as they both, in my experience, are usually pretty loaded with work. Often a sign of a good shop.
Another +1 on Bill Thalmann at Music Technology. He does excellent work with a specialty in high end tube gear.
+ another on Music Technology though turnaround times can be a but slow as noted above.
a bit slow that is...
The tech at Grammaphone in Towson is very good.
