Maybe it used a Crown DC-300.

 

Latter there was a  UPS like device that you could vary the line frequency. That the Stereophile and TAS guys liked.

Actually, a DC-300 and an HP sinewave oscillator was a pretty common method.  There was another device, though, made for the purpose.

Pacific Recorders Multisync MDA-1B.  All in one capstan speed controller, worked with most synchronous capstan motors of the day.  Sorry, couldn't find a picture.  I think there was also a competing product, but those memory cells haven't been exercised in a long time.
