A friend asked me to look over a player that was given to him and
determine if it needed any work before he paid to have it moved.
It is a Standard action and it played rather well with a music roll,
but with a test roll there were several notes that were not playing
and more that were not repeating.
Much to my astonishment when I removed the piano parts to check the
action, I discovered that the primary valves had been bypassed and
the tracker tubing was connected directly to the secondary pouch board.
The L-shaped board that connects the primary valves to the secondary
valves had been removed.
Has anyone had experience with this arrangement, and what would one
expect to be the problems? I know the primary valves are there for
The action appears to have been rebuilt about 20 years ago and is
still very tight. In checking out the problems with the secondary
valves, I found the valve lift and clearance between the pouch and
valve button was very sensitive.
