I have a Kimball upright with an orchestrion conversion.  When the
T1 hole in the tracker bar activates the Rewind it rewinds only
momentarily as the rewind valve isn't locking.  All the tubes appear
to be connected correctly and all three valves work fine.

If you have run into this and have a solution or need more data contact
me.

 [ valve 2 which activates valve three.  Green cuts out the action.
