Is there a good Krell repair service in Los Angele

The right channel of my Krell FPB300c amp went out tonight. This amp is about 5 years old, I average no more than 10 hours a month, very little usage. I am really surprised since the amp has such low usage. Anyone know some good repair service in the LA or Orange County area please let me know. The original boxes are in bad shape I fear it might not make to Krell if I ship it. Any advice would be deeply appreciated.

Regards,
