Hi All,  I'm trying to help a customer who has a 1922-1923 Kimball
player action that is nothing like the 1915 version.  He says there
is a control box of some sort with six connections on the exhauster
assembly.  He also says that the unit has auto-tracking and that the
only way to get the player to play is to disconnect the vacuum supply
to the tracking device.

It seems fairly obvious to me that something is not tubed up properly,
but I don't have any references about an early Kimball player action
with auto-tracking.  Also, there are four buttons in front of the
keyslip where you would normally find the three for Sustain, Bass Soft,
and Treble Soft.  Something tells me that this fourth button is part
of the solution to the problem.

I've asked him to send me a number of pictures which I can post in the
Archives or at my web site.  If you've worked on one of these units,
or have any info about the tubing, I would appreciate hearing from you.

Musically,
John A Tuttle
