Tube amp repair shop in/near NYC?

I think my tube amp has a defective bias supply as the output tube plate structure glowed ever brighter, the bias led came on and then the rail fuse blew. Trying another tube yield the same symptom (I turned the amp off when the bias led came on).

It may have been caused by shorting the speaker outputs when I was rearranging cables behind the amp and forgot to turn it off.

I can repair the amp or anything else you need. Send me a message through Agon. I'm in northern New Jersey and can meet you if necessary.

Thanks for the recommendations! It turned out to be two defective tubes that I tried sequentially, making me deduce incorrectly that the amp is defective. I called the first one, Ben Jacoby at HEAR audio in Brooklyn and he pointed out to that possibility. He also mentioned not to send the amp for repair before I made sure it is not the tubes, a very knowledgeable and honest person.

Glad you tried Ben and he was helpful. He's pretty well known in the NY area. What are the chances of trying two tubes in a row and both of them being bad! Glad you had a happy and inexpensive ending.
Regards Jet.
