The Bergytone BT-006 is an automation kit designed to put your player piano into
rewind at the end of the song. It is a complete kit of parts, ready to install. The
main difference between this unit and the old PPCo unit is the separation of the
valve block from the pneumatic, which makes the installation more compact and easier
The valve block is a dual valve design to improve air flow. It has dual mounting
holes so it can be mounted either flat or on edge.
It has a single control port that is connected to one of the last tracker bar holes,
which open at the end of almost every roll ever produced.
These photos show how easy it is to install. Drill a hole in the top of the BT-002,
then screw the valve block down. Prepare the linkage, then screw the pneumatic to
the side wall of the piano. Then connect the linkage and a section of hose. Run
the control hose up to the tracker bar and tee it in the appropriate tracker line,
and you’re done!
Here’s a couple pictures showing different valve block mounting, external to the
pump. The pneumatic in this case would be mounted above the keybed.
These photos show the valve block mounted to an HC Bay pump, and to an early Standard
pump. The grey hose is connected to a suction box like the BT-002
The auto rewind kit is now in production. The price is $165, which includes the
valve, an actuator pneumatic, 3 feet of hose, control line hose, elbow, linkage hardware
and detailed instructions.
