In the 100807 MMD Gary Rusnak asks for help with a play/rewind problem
he has encountered after removing and re-installing a player action.
Not being there to look at the problem, I can only guess that the tube
that controls the automatic rewind was somehow disconnected. Not
knowing what kind of player system he has, I can speak only
generically.
First, find the valve that controls the auto-rewind. The way to do
this would be to take the input supply to the rewind pneumatic and
follow it backward to its valve. Now look at the input tubing to this
valve and find out which one of them controls the rewind. (On my Duo-
Art the same valve controls both repeat and rewind; so you need to know
which is which). With that tube in hand, you'll have to follow it
backward to where it is disconnected (or perhaps connected but broken).
If you have a helper, have one blow on the tube and the other listen
for where the air is escaping. Try not to pull on the tube too much as
you don't want to lose its location.
If you find it disconnected, and don't know where it should go, good
luck. Find a nipple that isn't attached to anything. If you discover
that it was disconnected from the tracker bar, find the free nipple and
connect it. If it is a reproducing piano, then you'll need to know
which hole controls the rewind and make sure that's the one you
connect.
