I am attempting to restore an old player piano, and have come to a
point where I am stuck.  I have the transposing tracker bar, but
naturally, as the piano is 75 years old, the rubber tubing connecting
the tracker bar to the lead tubing is all dry-rotted and broken.  I
have yet to find any diagrams telling me which tubes go where.  I'm
sure there's a pattern, but I don't want to mess anything up.  Any help
in this matter would be much appreciated.
