Have you looked for a crystal oscillator on any of the PCBs?

You should be able to fairly quickly find the relevant PCB since it
should be hooked up to the tacho-sense of the capstan wheel.

I fortunately have Tacho-drive on my Studer B67, but sadly enought I
only have one of them, so I can not run them in parallel for such
experiments.

Cheers,
Magnus
