Good amp repair shop in L.A.?

Audio Specialist seems best with oldest type of equipment.
For anything else they don't seem to do in depth diagnosis/repair as I have personal experience with repair which was later inspected by manufacturer.

Brooks and Tom.

Brooks.

BROOKS! worked magic when it came to my Jadis, and La Platine.

In addition to the others mentioned, Mitch Singerman in LA might be able to help depending on the equipment.

I say go with Brooks. I used Howard and he took forever and actually charges more. Tom will usually get your piece fixed in less than a week, unless special parts need to be ordered.

2nd Howard in Studio City...What Brand amp would help..

Brooks has an outstanding technician. His name is Tom Carione. From personal experienct, I would avoid The Audio Specialist.
