Stewart,
Thank you for valuable insight for the Uher. I had wondered if the rubber on the capstan flywheel might be a problem, but I was thinking about wear, not excess friction. I will look for adjustments for the driver and see how that affects play speed.

...I would examine the capstan wheel and its stepped flywheel driver. The angle and tension that this stepped flywheel contacts the surface of the capstan wheel can make all the difference to reliable running in these machines. If wrong, friction could be softening the rubber surface here after a time - leading to more friction and slower running. If I recall correctly the stepped flywheel position can be adjusted....
