Repairing an Electronic Organ

Step 2Digging in

Digging in
The first effort was just to make the tremolo work again.

The tremolo is a speaker set behind a rotating foam wheel with a large slot cut out to make the sound wobble in that particular way that pipe organs do.

Our wheel didn't spin. To make it do so, we spun it manually, dislodged the nut placed on the rope, and that was all it took.

The unit is actually called a Leslie speaker. Although not a true one like the fridge units that were sold with the rotating speaker on top and a standard speaker on the bottom, it follows exactly the same principle. I recently pulled one almost exactly the same out of an old and now defunct organ but it needs hooking up to a power supply. Have you ever worked with turning these into a standalone speaker setup?
