Open reel recorders used fixed heads. The tape speed is determined by the
accuracy of the rotating speed of the capstan and the electronics that drive
it, and to a lesser extent the weight of the tape as it shifts from supply
to take up reel.

Yes, it requires a competent technician. He could also check the tape speed
and do maintenance on the transport if required as well as the electronics.
Video Works! Is it working for you?
