The MF website lists several dealers in California. Perhaps one of them can help you. Or you could contact Randy Bingham (MF sales manager for North America) to see if he has any recommendations. Contact info is readily available on the MF website.
Where in California are you based? I may be able to make a recommendation in the SF Bay Area. Also curious as to what is the problem with the amp, I have one too. Another option is to contact www.audiohigh.com a MF dealer in Mt. View, CA, they may have a recommendation. Andy
