Hammond A-102 to Leslie 760

[Rileyl4]

I would really appreciate some help on connecting my A-102 to my new to me Leslie 760. The organ did have a Leslie hooked up to it at one point but when I got the organ, the organ is all I got. The new to me Leslie came with a kit and all accessories needed to hook it up I'm just not sure how to take care of it. The kit it came with is a 012617 kit and both tremolo/chorale and echo/main/ensemble switches.

Sorry, but Icannot help you with the interconnection. However, I am curious about the Echo/main/ensemble switch. Does it allow you to switch between internal and the remote cabinet? I have an A100 and a 21H Leslie. I'm trying to find info on multi-speed upgrade options. It seems that most of what I find is several or even more than a decade old.

I noticed that no one responded to your post. Have you found the info that you need elsewhere?

Hello,

I beleive it is a 7271 kit with 012617 console connector.

I have not really revived the info I need. The gentleman I got the Leslie from had it retrofitted with the E/M/e switch so you could have both internal and Leslie going at the same time along with the different speeds instead of the traditional “off” no rotation. The AO-39 pre amp seems to have a section on it in which you would connect a external speaker, IE Leslie. At least that's what I see.

Look at: http://www.captain-foldback.com/ Leslie / leslie pin out tab. Your Leslie 760 should have a 9 pin connection. Do you have a 9 pin cable and a 9 pin kit?

The 012617 silver box and the switches you describe are all part of the standard '26-1' kit for 6 pin leslies like the 147. It's the wrong kit and it won't work with a 760 so is no use to you - unless it has been modified to be a 9 pin kit.

If not, then your 760 needs a 9 pin leslie kit. Officially, it's a 9510 kit that you need for A100 to 760, though there is also a 'standard' 7270 kit that will work just as well. Sell the one you have and source the other one. Or go back to the seller and get them to supply you with the correct kit!

If you have MEE and Leslie speed half moon switches then you can decide whether the sound comes from the organ, leslie or both, and you have the choice of tremolo, chorale or rotors stopped, as shown on the speed switch on the 760 speed switch. This 'retrofitting' business makes no sense to me at all and sounds like rubbish!

The reverb will still come through the internal reverb speaker of the organ, if you want 'remote' reverb, then use a small unwanted hifi speaker capable of handling around 20 watts on in place of the internal reverb speaker. Hang it on a wall near the leslie!

I agree! Some models are VERY close to one another and a slight kit modification makes sense - but that's not the case here. Also, 9 pin connectors are getting hard to find.

[Von R. Colborn]

B3-Guys do sell the 9-pin connectors, hoods, and wire. They aren't cheap but they are available.

[Rileyl4]

The kit came with a 6 pin to 9 pin connector so it should be fine. If I have to get another kit that's fine but I do believe the one I have should work.

[andyg]

A plain 6 pin to 9 pin connector? Hmmm. Could be a recipe for a big bang. Speed switching is totally different between 6 and 9 pin systems. 6 pin 26-1 uses mains AC, 9-pin simply switches ground from one pin to another (or to neither to stop the rotors). You need to be VERY sure about how things have been modified before you plug anything in.

Do some research on the pin-outs on Captain Foldback's pages, and perhaps take some photos of what you've got and post them here so we can give you more advice.

Building a 7270 kit is not rocket science either! The schematics are here: http://www.fishorgans.com/leslie_kits/007270A.pdf

"The kit came with a 6 pin to 9 pin connector so it should be fine. "

Thanks for letting us know. I always thought that hooking wall power (mains voltage) to low-voltage DC circuits would be a problem.

That looks appalling! Apart from the fact that it's very badly done, there's no way of telling exactly what has been done, and the one thing that would definitely be needed is not there. That would be a mains voltage relay that would do the ground switching for the 760's speed control.

Go for my earlier options. 1) Sell the 26-1 kit and get the correct one. 2) With the help of the available schematics and the parts you already have (apart from the half-moon which would have to be replaced with the correct type for 760 three speed operation), convert the kit to work with the 760.

Plug this one in as it is at your peril.
