Hi MMDers,  I have a customer who has a newer Kimball E or F that is
having a roll speed issue: the Tempo control doesn't do anything when
playing a roll.

This Kimball player action is very susceptible to a piano tuner
accidentally crimping the wires when the action is lowered and screwed
back into place after tuning, and this is exactly what has happened to
this one.  After clearing the short circuit, it still doesn't fix the
speed problem.  I think that one of the transistors have blown which
has either damaged the speed regulator or the electronics thinks that
it is always in the rewind mode.

I would like to find the schematics for the Model E and the F since
I don't know which one is at the customers home.  It would be great
if you could email the files to me directly.
