I live in Sacramento. There is a club--Sierra Nevada Audiophile Society. The website may not be up to date but here is the link. http://sierranevadaaudiophilesociety.com/
I also know a local technician who might be able to repair your McCormack. My friends and I all use him.
I cannot find a way to send you a private email with my contact information. If I could, I would hook you up with the Audiophile Society president and the technician. I do not want to post their (or my) information publically.
