Now had I known that! I was acting upon the assumption that like most other
drives the 60 Hz RL02s would not work without significant changeover on the
German 50 Hz power. Thank you very much for that info, next time I will
know better and secure the drives.

In fact, my "RL01/RL02 Disk Drive Maintenance Course" textbook says:
The circuits controlling the drive motor in line are
located on two modules. The drive logic module
decodes the speed of the rotating spindle and sends
the signals to the AC servo module which controls
the drive motor's duty cycle.
