Gary Starr inquires about a tubing diagram for the Cremona shut-off
system [130128 MMDigest].  I assume we're talking here about an "A"
roll piano.  I never found a tubing diagram, but it's dead nuts simple.
I just spent an hour looking for my Cremona folder (unsuccessfully,
of course), but here's some help from memory.

The coin trip hole in the tracker bar is the last on the right, hole
number 65.  That tube goes to a pouch and valve that admits vacuum to
the little pneumatic in the coin accumulator.  You may have a tubing
error, or perhaps a line came off, or possibly your trip pneumatic is
shot.

If you need further assistance, contact me directly.
