Estey Player Piano With Amphion Action
By Paul Rumpf

John Phillips asks about the Estey player with Amphion action.
From the picture it appears there are three sets of dual cutoff
boxes.  My guess is that the _two_ 'H' shaped tees are to couple
a single control signal to the control (on/off) ports on the three
boxes.  If this is so, then the three boxes are used to cut off
six separate pneumatic functions.

What are these functions?  I don't know, but there may be clue
given from the tracker bar.
