[CAH]

I'm in SF Bay Area, California. My Stairmaster 4400PT suddenly started "racing" with speed control no longer functioning. According to experts, the alternator may have gone bad. Since unit is pretty old (> 6 years), I'm seeking a local service organization or individual who can not only fix the unit, but refurbish cables, bushings, and such that are probably near end-of-life.

Any suggestions? I'm in area code 925, near area codes 408, 415, 510, and 707.
