California Audio Lab -are they out of business?

Hello to all. I have a California Audio Lab DX 1 CD player (solid state) with a 60 HZ ground buzz. Had a local flat-earth repair guy take a look at it, and, no surprise, it baffled him. I did a Google search for a Cal Audio Lab website,nothing came up. Are they out of business? Does anyone know of a decent repair facility that can handle the repair? Many thanks for any info. Bob
