Thanks for that intersting link. Polyphonic too!
I wonder if one still exists or parts of it in a museum somewhere?
Wear rubber gloves when playing it! :-)

I believe that one problem with this device would have been that the
line frequency would modulate the tones being generated - a sort of
tremolo effect, no doubt. Hey, I'm sure Hammond or Leslie used the
effect in some way too.
I've thought that a good way to solve this would be do a DC coil, but
then you need de-Qing diodes and charging inductors.
Good HV design practice, the motor and spinning shaft are at ground
potential. More than one TC enthusiast has burned up a RSG drive motor.
and he improved it later..
I note this: "Obviously, in order to produce chords, it is only
necessary to supply a current of sufficient intensity to permit of a
plurality of different sets of sparks at the same time consequent upon
the pressure of the corresponding number of keys."
So M. Desilets also appreciated "mo' power"
