organ leslie for guitar

marcrochotte · 10-13-2009, 01:32 AM

i tore apart an old wurlitzer organ and took the leslie out. i wanna use it with my guitar. i can tell how to wire up the speaker, but i dont know how i would wire up the on/off and slow/fast switches. any help would be appreciated. thanks! i have attached the schematic that is on the cabinet

Need the relay coil voltages - can you spot mfr and model numbers on them?

marcrochotte · 10-14-2009, 12:19 AM

i dont know which of these numbers you want, so heres a picture..

Those are the motors. The relays are different items. IS there a metal control box of some sort that those motors connect to? I would put up a picture of a relay, but there are so many shapes and sizes it would be pointless to select one.

If you have a control box, that is where the relays would be along with the triacs in the schematic. If all you have is the motor assembly and the spinning baffle, then you will need to build a control box.

yes there is a meatal control box, i have the whole leslie sectiion, it was connected with 5 wires to a different area, i just dont know how to wire it to switch it on and off and to change the speed.. there are 2 wires for the speaker and three other wires..and there is also an ac cord..

That fits your schematic. Would the three non-speaker wires be orange, white, and violet, by any chance?

Can we get a picture inside the control box? Specifically the two relays - the things with the wire colors I mentioned going to them.

marcrochotte · 10-14-2009, 11:43 PM

yes they are those colors, the relays dont have any numbers or anything written on them..

Ah. Looks like reed relays, which is fine, since they are only controlling triac gates - very small currents.

The relays run on separate power from the rest of it. You plug the box into the wall, then energizing one relay or the other - not both at once please - turns on one of the motors.

The orange wire is common to the relays and would be your ground. Violet is the slow motor and the white wire the fast.

I don;t know what voltage the relays need, but I'd guess 5v or 12v. DC voltage though.

Make up a small DC supply, ground to the orange wire, then apply the + voltage to the violet or the white wire. That shoulod turn on the relay. And that should turn 0on the motor it controls.

For experimenting, I bet even a 9V battery would work.

Is that relay in the foreground burnt up or is that just some brown stuff dripped on it?

just something that dripped on it i think..it still worked fine when the organ was on..thanks a lot for the help!
