Hi Duncan:

The problem with the C3 as described to me sounded like one I had seen
several times before, and has to do with the tone wheel generator.  The
tone wheel assembly hangs from a spring suspension to reduce the amount of
mechanical noise coupled to the case of the organ, where you would probably
hear it in a home environment.  Instructions with the organ state the tone
wheel assembly should be locked down when moving the organ, but some people
on tour with a Hammond fail to do so.  The result is the tone wheel
assembly will move around an inch or two, it will swing around to the
limits of the spring suspension when the organ is traveling.  Over a period
of time, the continued flexing will break off some of the 100 or so wires
coming off of the tone wheels and leading to the keyboard/drawbar assembly,
they typically break right at the terminal strip on the tone wheel
generator.  This will alter the sound of the organ on certain notes, you
will have either a missing fundamental or one or more harmonics.  The
solution is to lock down the generator and resolder the broken wires, which
is what I told the guys with Triumvirat to do.
