Does anyone have a technical manual to the old Pianocorder system?
Three of these units have popped up within the last week.  From a
technical standpoint seem quite archaic but they are still working with
the exception of a few small things, like the volume control, speed
control, loud pedal, etc.

I understand they were not UL approved.  Are they safe in a customer's
home?

Thanks to all for the suggestions on leather belting.  They were
sincerely appreciated.
