Anatomy of a WurliTzer Theatre Pipe Organ
SWITCHSTACK Action - Top Board
The board is upside down, looking at the inside.
The connecting wires have been installed at one end.
These connect the pneumatics, below, to the switch pull wires above.
The red bushing cloth on the loops prevent wear and noise.
You can also see the cover plates over the unused holes. All action positions
were drilled in this chest whether needed or not. The holes in the top board
were covered from the inside while the unused magnet holes in the bottom board
were covered on the outside. To add extra actions it only needs the covers to be shortened.
