Anatomy of a WurliTzer Theatre Pipe Organ
Manual Chest Manifold.
The narrow manifold on the "C" end of the chest had two sections. One was for the
Vox feed, seen at the top, and the other was common to the other four ranks, from
which the Main Trem was connected.
To provide a seperate Tibia regulator and trem system the four rank section had to be
divided up to isolate the Tibia from the others.
