The Leslie Combo Preamp was a chrome wedge shaped box (stompbox) that was designed to be used with the Leslie speakers with the un-balanced input amplifier, i.e. 147, 145, etc..

It has two 1/4" inputs, a fader for each input, a foot-switch mounted top-middle, 115VAC power cord, 6-pin connector for the interconnect cable. These are available used.

Aftermarket pre-amps are available that perform the same function as the Combo Preamp but are designed to work with a variety of Leslies: balanced, un-balanced, 6-pin, 9-pin, etc.. (Trek is one maker of such devices.)

Thanks for the specs, much appreciated!
