[HAM] What model is it?

A big ol' gang switch on top of the chorus genny, as many poles as there are
tone wheels, single throw.  This is what you are moving when you pull the
chorus "drawbar" out.

Looking at the diagrams in the technical manual, the chorus generator tones
run from freq #s 56 to 91, and they are connected directly thru a 'chorus
control switch' to the filter input terminals on the main generator, so the
chorus tones are mixed there with the corresponding main tones before the
manuals, and there's no way to separate them after the keyswitches/ busbars
that I can see. Interestingly, half of the chorus tonewheels are double, two
wheels with different #s of teeth stacked together and spinning in front of
a single magnet/coil.

Does anyone here know exactly what is the 'chorus control switch'? I couldnt
find any details on it.
