Quad 12 Speaker Repair

I live in the San Francisco Bay Area and in need of getting a Quad 12 speaker repaired. It fell off its stand and broke the posts off. It also suffered a chip in the cabinet. If I can only get the posts fixed, I can live with it, but I would also like to get the cabinet fixed also. Anyone know where I can get these repaired. I can ship them to a repair center but would prefer a quality repair facility in the Bay Area.
