  • removing built in leslie

    Hey guys, first off I want to say thanks for the heaps of information that i've gotten from these forums, this is my first post but I have been browsing for a few years. ANYWAYS, I am in the process off removing my leslie rotating speaker on my hammond 8022m to use as a standalone speaker for keys/guitar/maybe even some vocals. Its just a little project than anything too serious. I've removed the leslie and I am working on removing the power supply and whatever else needs to come along to make it work. So far everything is fine, but im having trouble getting the switches that toggle the leslie on/off and fast/slow. they are attached to a maze of wires that attach all over the organ. Basically what I am asking is which components are essential in making the leslie run? I can and will upload pictures as I go. any help or tips would be awesome, thanks.

    Basically, you are asking how to control a frog's leg after removing it from the frog!

    The controls built into the organ won't likely be useful in this case.

    You just need some switches and/or relays to supply power to the motors, and an amp to power the speaker.

    I don't know how useful the amp from the organ could be...what is an '8022m'?

      If you don't use an amp, and use it as a cabinent. You can get a 12v wall wart, a 12v relay, a two plug electrical wall socket and box, and a power cord, on off button, then a foot pedal or switch to control leslie fast slow. I believe thats all the ingredients for making cheese wedge work for that purpose. the speaker might be 8 inches also so check the ohms to match to an amplifier.

        Even easier than relays, get a two-way light switch from Home Depot, and a device box to put it in...

        You will also want a better speaker, a decent amp, and a good cabinet to put it in.

          Two way light switch won't pop on audio? Good to know.

            If it does, add some arc suppression capacitors. But since the audio and AC are [mostly] isolated here, I don't think it would. My 6C test rig uses a regular light switch and it doesn't pop. Of course, it is switching far less current.
