Hey there guys. I have an old organ with a working Leslie in it. I want to know if it is even remotely possible to take out the leslie and put it in an amp.
Thanks guys

The leslie is a speaker cab. Some models have built-in 40w tube amps.

Inside the wood cabinet, the treble horns rotate on a platter (one of the treble horns is actually a dummy used as a counter-weight). the subwoofer points downward where a ramp rotates. the ramp and treble horns rotate in opposite directions and are connected to a 2-speed motor.

You can certainly remove it and use it in an amp. If it has the built-in tube amp, you can use it AS an amp.

edit: found some pics.
