If the organ has a headphone socket, no load will be needed. Most organs
should be using push-pull semiconductor amps, and won't give a @#$ about a
load bing there. For tube amps, proceed with caution.

Not the case at all. Some of them even use Jensens.

As for the speed - there are two basic tupes of leslie motor, the single and
the twin. If the organ offers "chorus (celeste etc) and tremolo on the
control panel, it has a twin motor, and two speeds. This is what you want.
Most older Lowreys are like this, though some such as the Symphonic Holiday
use a small leslie with only one speed. 

Avoid Yamaha - they use a rotating speaker sometimes, and sometime they just
use a VCA (Yuk!)
