Any good HiFi Audio Repair shops in S.F. Bay Area?

I need some referrals for a competent Audio Technician to help a friend have his Meitner PA-6i pre amp repaired. His calls to the guy handling Meitner repairs have been futile; any suggestions and phone numbers are appreciated. Anywhere in the Bay Area from San Francisco to San Jose would work. Thanks.

I third Nick and second Scott....have used both for years and both are excellent.
