Leslie Control Center vs. Half moon switches . . .Looking for advice.

[ts808]

I have the "Leslie Control Center" with two white switches on a B3, controlling a 122. These switches are Ugly and noisy!
My understanding is that my current switches are to control a Leslie and a tone cabinet. Since I have just one Leslie could I install a half moon switch, or two? Are the switches interchangeable and are there pitfalls to watch out for in making the change?
Attached a picture of the current switch. Thanks to any and all! T

Never understood why they tried to reinvent the wheel with that type of switching system.

I get the footswitch, but not this...

I believe that this switch was made for a spinet or E series organ or any organ with a self contained amp and speaker system such as an A100. If one is used on a B3 or C3 it would have to have a Leslie and a Hammond tone cabinet.

I imagine the wiring inside my current switch is quite a bit more complicated than the wires in a single half moon. If I could locate the correct two wires could I wire in a half moon and leave the extra wires cut and capped? And which two would they be? Thanks, and Amen to 8paint's remarks......they could've at least added some lights and maybe a spinning spiral like on the 4-banger Leslie model! I got to switch switches.

Thanks, T

Follow the wire from the control center to the kit inside the organ. There is a white molex connector. Look at the connector and note one end is close to the edge of the kits circuit board while the other end is more in the middle. The first two wires on the outside end of the molex connector are for switching fast and slow. Simply parallel your half moon switch to those wires. You'll have to park the control center switch to fast so the new switch can work. You can leave the control center switch where it is or hide it inside the organ.

Geo,

Did as you suggested and it looks like it's the brown and red wires I want. Can I cut those two and solder the wires from the half moon switch to them, or should I just remove a small section of insulation from them, leaving them connected. I could then solder the new wires to the exposed areas? Thanks a LOT! T See pictures.

You can cut them and connect your half moon switch. Removing insulation and connecting allows both switches to work.

Geo,

Thanks so much for your help! I really don't like the Leslie switch I have and will be happy to connect a half moon or maybe a foot switch. There sure are a lot of wires in and around the Leslie kit inside the organ!

Nothing to it. Pull the Molex and remove the control center. Install the Half-moon and connect the wires to pins 1 and 2 of connector J3 of the 6122 board (J3 is labeled, and pin 1 is labeled). You can also connect a jack for a footswitch in parallel. The only caveat is that if either switch is in the fast position, that switch is the one that must be used to take it back to slow. IOW, use one or the other.

Note that if the speed switching ever fails, the problem is likely that R1 and/or R2 have opened up. I've had this happen on two or three units. (Haven't had any other 6122 problems.)
