San Francisco bay area Unison Unico repair

I had an accident when connecting a bunch of component including a Unico. It now makes only noises/vibrations. Does anybody know a reliable shop in the San Francisco bay area that can repair it? I'd really appreciate any pointers. Thank you.
Nick Gowan, @ True Sound, in campbell, is the place that most of my friends have gone to get their equipment repaired, particularly tube equipment.

Anti, There are several, but call The Sound Well in Berkeley. They charge to diagnose, so make sure you want it repaired.
