Leslie hookup help!

[Hamman]

I agree with the "make your own kit" theory. However, that D152 has internal speakers and unless the OP wants both the Leslie 147 and internal speakers going at the same time...all the time...he will need a MEE switching kit.

Ok here are the picks of the 5 pin and 6 pins connectors on the organ

Those sockets are wired for a 122 type Leslie.

Here we go again with the kits ;)

So that means there would be a way to re-wire to make it fit the 6W type Leslies right?

[geoelectro]

Yes. The 6-pin socket can. Terminals 3 & 4 are already wired right. (Power) Pin 6 connects to a G terminal on the organ preamp. Pin 1 goes to ground. (Chassis) This takes care of power and audio. At this point you could plug in the Leslie and have sound, but no switching. Pins 2 & 5 should be vacant for this test. For switching, a jumper goes from pin 3 to pin 2. The Leslie switch has 2 wires. One goes to pin 4 and the other to pin 5.

122 wiring requires a “kit” that I didn’t see in your pics. Running pin 6 to a G terminal on the preamp bypasses that kit which is needed.

There is AC mains voltage here so caution is paramount. The gray and blue wires are AC power.

Geo. I really appreciate your reply. This is all new to me and I am learning the rope here :) So it is safe to plug my 147 right in that 6 pin socket?
I have a tremolo switch already. it has this 2 pin plug. I could remove this plug and wire it on pins 4 and 5 for switching?

[geoelectro]

Not until you do the steps for pins 1 and 6 AND remove any wires from 2 and 5, THEN a 147 can be plugged in. Once that is working correctly (no hum etc.) add the switch to 4 and 5 and a jumper from 3 and 2.

The problem with me describing this is not knowing your level of understanding and possibly assuming you do know certain things. There is AC main power in here which is dangerous. I tried to list the steps in order of safety importance.

There are 2 G terminals on the preamp. I can choose any one?

[D152]

Another question, there are wires going from the 6 pin connector to the 5 pin connector. Are those connections still required?

[geoelectro]

Either G terminal. The other 5-pin jack I am assuming you will not be using, right?

Geo

[D152]

I will not be using it no. Unless it could be used to add a "main echo" switch??

[geoelectro]

It can be BUT, it's involved.

Any _balanced input_ Leslie (31H, 21H, 22H, 122, 142, 222) needs an expensive kit due to the way speed switching is applied in those models

Any _unbalanced (single ended) input_ Leslie can be made to work fine with just standard switches, resistors and outlets. No kits needed.

Thanks guys for all your answers. I will execute this and tell you how it goes!
