I'm in the San Francisco Bay Area and am looking for a place that
still services older '60s and '70s stereo equipment (tube and early
solid state). There used to be a bunch in Berkeley and even San Jose,
but all the one's I used to know have gone belly up. Anyone still
know of any serious retro audio repair places? Looking for a friend
who needs work on an early H-K receiver. Thnx.
