NYC Repair of Revox B795 direct drive turntable

A non-technical friend in Manhattan, NY asked where to take a Revox B795 direct drive turntable for repair by an experienced tech person. I only know it has stopped working, but no details, except it has worked correctly for decades, until just recently.

Also, if you can suggest a replacement turntable with equivalent automatic operation, in case repair is not practical.

As a last idea, whether anyone in the NYC area has an operating Revox turntable they are willing to sell locally.
