Any repair center for Yamaha DSP in San Diego, CA?

My buddy is trying to locate a repair place to take his DSP A2070 A/V Receiver - the selecter switch is driving him batty, it cutting out. Or do you know of any location in Southern California that carries Yamaha parts for him to swap out?

Taken directly from the Yamaha website. Give them a call. Sometimes these websites have invalid or old info.
Thanks! I will pass this along to him...
