    My new 1960 RT-3, Leslies, Cables, and questions

    Hi everyone :)

    My new 1960 RT-3 with some things I don't understand and a converted 22H. I've been reading enough to know not to try without knowing. I played it from the 1/4" output jack under console. Worked great. My brother gave me the organ. He sold his 31H and some other Leslies 5 years ago. I found the converted 22H in Yakima. I got some others also, but this one I want to get going asap.

    A bunch of pics of organ, cables, relays, and the speaker in question.

    No marks on Leslie adapter.

    5-pin to 6-pin cable

    RT 3 and accessories by unoh7, on Flickr

    I want to get the 22H hooked up and working. I have a on/off half moon you will see in pics.

    Also some 1/4" outputs, one with toggle.

    What kind of 6-pin does that 22H need? Don't know the kit but can open it further if you need.
    How can I tell 6-pin type if leslie adapter is unlabled? I can pull it apart, but wanted to ask first.

    Help! I can solder and have read a bunch of threads about making cables but I'd like some input before I try anything.

    Thank You.

    Organ bought for the then new Unity Church in Seattle in 1960. My brother was UW music student and made friends with organist. Later, late 80s he overheard a discussion about getting rid of it, and bought it. He left the chimes. I just moved the organ to my home. Very excited to get it going here.

    Your brother had a 31h? Was it what was hooked up to Rt3?
    You have a 22h... with a two speed upgrade? It should still be a 6H pinout. It all looks like you could plug a 6 pin cable in Leslie and brown box with 5 and 6 pin female sockets in the RT3. Use 6 pin to 6 pin cable from organ to Leslie. You could flip over the 22h amp and check the pinout is still 6 h and take the brown outlet box off organ inside and observe pinout. You can find more about Leslie pin outs by Searching (uncle Harvey’s pinout guide). I hope this helps. I am responding to move you forward, the pros will more than likely chime in soon. Nice Organ and welcome to the forum.

    ps Leslie 760 and not sure about 105 in flicker photos are Not 6H pinout.....!!!!!!! Do more research about 760. Great Leslie.

      Just read other thread Rt3/825. I do not see any 9 pin connectors in photos.

        Thank you Mckenzie.

        I read further realizing 6H was likely both in organ and speaker, so I grabed a clean looking cable and did exactly as you said. IT'S ALIVE!!! For sale signs going up all over neighborhood ;)

        I did realize 760 needed 9 pin, which I don't have and I will need to work on. But now I'm going. Half moon works a treat. Mystery toggle on gold 1/4" shuts off Leslie, and i'd bet diverts output to 1/4" Pedal solo with all pipes incredible.

        Ed, the wonderful 80 year young man, who sold me speakers, had never heard of the 760 and 122 playing together. But some descriptions of cable conversions 6-9pin DIY, make me think they can.

        WTF is the 5-pin output on the organ for, PR-40? I have a male 5-pin to female 6 of some length and wonder if that would drive the 22H the same as the 6 out? Do I dare try?

        Can organ drive both outputs, the 6 and the 5 at same time? Would half moon control both?


        How do you like that little 106? I could not leave it. Don't know what I'll do with it. It has a simple three wire input and seperate 110. Might tie it to 1/4"

        Yes my brother had a tallboy, he let it and others go 5 years ago but kept all cables LOL. I narrowly missed 31H in Boise for 500. But 950 for these three I thought was very good deal. We'll see how the 760 runs.

          well, maybe the 760 will be going soon.


          9-pin by unoh7, on Flickr

          Ed brought me back to his house from the storage to give me this, which I thought I had no use for. He knew exactly what he was talking about, which makes sense because he was auto repair instructor in Montana high school, amoung other things.

          My thought is to adapt that 5-6 pin cable which is good length. On 6-pin side in install the above female socket. I think I saw Wes mention 760 needs a single G, and any three way switch would do. Then access the switching lines close to the 5-pin connector on organ, and run a second switch. That cable is long enough and in good shape. Butchering at both ends but to good effect, no?

          I just need pin diagrams for 760 and the 5 pin (to check for G and eliminate one if there are two)

          What is cheap 3 way switch which I could mount on organ?

          Should I cap the 110 from organ socket and use the guts above to plug 760 into wall? Safer?

            The 5 pin socket was Hammond Standard for Pr40 tonecabinet etc...(so the 5 to 6 pin cord is extra parts not very usable.
            You could plug the Leslie into this socket, but you loose speed switching and the Leslie will be stuck on fast. I am sure there is way to add a nine pin female socket at organ and add the 760. The 6h setup has a transformer so you switch DC voltage at half moon. Instead of VAC like a 6W pinout.

            Try a new thread in Leslie, tonecabs forum... Asking about, combining a 9 pin 760 and 6h 22h. Do you want both Leslie’s and one speed controller? Do you want to be able to turn one Leslie on off, and play one, two or both? Each situation requires different approach.

              Not quite true. 5pin-to-6pin is standard hookup for 6H Leslies on "3-series" Hammonds.
              Current organs: AV, M-3, A-100
              Current Leslies: 22H, 122, 770

                That’s why I consider you one of the Pro’s. I was under impression one needed to wire a 6 pin socket for all 6H on console end. Thanks Magnus, learn something new everyday, one perk to being a human. I guess I need to read up more about 5 pin hookups.

                  Thank You guys, my idea is use the 5-pin outlet only for G and main if I need main from organ. Can the 760 take 110AC through 10 pin? Then I would use extra wires in the cord for a three way switch, which I'p tap into directly. Id' access them directly and cap switching from organ outlet I'd have a seperate switch for 760.

                  What I really want to know: can both 5-pin and 6-pin outlets be in action at the same time? Will this be too hard on power mains in Organ?

                    Yes, you can run both outlets. Yes there was AC in the nine pin cord.
                    I only just received my first true 9 pin connector kit for a Leslie 900 in a CV. So I have little experience there. I have always used the preamp pedal before, which is inefficient.

                      Huge Help McK:)

                      I tried 5-pin. Works but no speed change.

                      Another question. At low speed the 22H has a soft thump thump thump in lower side. Is that normal, what might it be? I will post also in Leslie forum, but any thoughts here apreciated.

                        Check to see if scrim cloth is hitting side or back, rubbing underneath or over top lower rotor.

                        Update. I guess I should have asked does it sound mechanical or electrical? Does it make thump sound with organ turned all the way down? I have chased rattles all around a 147 before. Before long you will be wanting to look at grommets, bearings, motor springs if needed. That could create mechanical slop with age.

                        Just read Leslie thread in other forum. Good luck. Much more expierence there.

                          Thank You again. It's mechanical I believe. Listen, every post you make I learn something. Scrim cloth? Now I'm gonna look that up. I'd love to hear your impression of the noise:
