  • Leslie 6155-1 9-pin connector

    I bought this connector online with the idea that I could at least use the box with the 9-pin socket to make a kit to connect my Hammond CV directly to my Leslie 900.
    I have been using the Combo Deluxe pedal to connect, and have the CV rheostat cam pulled all the way up (I am still working on acquiring or building an expression pedal). Any other position of the rheostat distorts excessively. I understand that this position of the rheostat, however, will also filter out the maximum amount of mid-range tones; so I am hoping the direct connection will give me a more balanced tone, in addition to having half-moon switch control at the console.

    Is anybody familiar with the 6155-1?

ID:	790529 It looks like I "might" be able to just plug into the 6-pin receptacle on the organ, but I don't understand the reason for the relay inside the 6155-1 (looks like it is connected to the Chorale/tremolo switch socket).
    Also, my CV has a B+ power supply installed already. Would I have to either disconnect that, or a wire in the connection kit?
    Ultimately, I may have to just trace all the wires, make my own diagram, and try to figure it out myself.
    BTW, the 6155-1 also has an "adapter" of sorts that, as best as I can figure, is plugged in between the 9-pin cable from the leslie and the box. There are two wires that go to the Echo switch socket - so I am thinking this kit was for an organ that had internal speakers? I do not have any other speaker for this organ, and I haven't got the reverb channel working yet on the Leslie, but presumably, I could use that to control the reverb if I did get it working again?

    Rare bird can't even find that on the Harvey/Casino lists.

    It looks like with the relay, the usual speaker/brake EBY connectors that it was meant to connect to a rotor system and a speaker.

    Perhaps someone will chime in to the rescue.

      The only other reference I have found is this from the forum where someone apparently had one bundled with a Leslie 205.
      https://organforum.com/forums/forum/...and-205-leslie
      And a quote from Andyg on the 205; "...the 205 was never intended to go anywhere near a Hammond."

      It would probably be safest to just remove the relay from the circuit and ignore it?

        My tendency would be to put it up for sale keeping it whole so there would be an existing model of that version for someone else to use rather than gut it. These units are not made anymore should go without saying.

        But then how many out there are looking for that particular piece? Something for the Smithsonian? Do they have the room?

        As the saying goes, "can't have everything, where would you put it?"

        But that's just my thinking.

        Fresh relays can be found these days in case one is in need of such parts.

        Or one could hang onto to it to scavenge parts...

        I remember asking Jerry Welch if he had a controller box for a Fender Vibratone. None he said. You rarely see them come up.

        I'm finding that the slow motor spring for a Vibratone (again Fender or the 'Leslie' version of that model) is non existent. The motor stack on a Vibratone sides sideways so the spring is not supporting the motor from going up or down but sideways which is a whole other spring wind. I sent Rick P at Tonewheel a photo of the one I pulled out of a rotor system from a Hammond T that has the vertical mounted system like a Vibratone and he'd never seen one to even have the part and he told me he didn't imagine that the spring I showed him would look like that.

        Information gets lost, the people that would know pass on and we're left with a Beyond Thunderdome situation where common things like a record player the operation of which gets lost upon a future society.

        Hammonds and Leslies are heading in that direction.

          After verifying that all the wiring was correct for my application, I was planning on using the kit entirely as is (with the exception of bypassing the relay - I wouldn't even bother to take it out of the box).
          Perhaps someone will stumble on this thread in the future if they google "Leslie 6155-1". If they reach out to me (perhaps by just posting here) I would be happy to send it their way (after arranging a suitable replacement of course) - it seems the 9-pin female connectors are increasingly difficult to obtain - I assume nobody is manufacturing them anymore?
          BTW, are you telling me the spring in the Leslie motor in my T-412 is a rare bird as well?

            Understood.

            Yes the T-412 has that sideways rotor system on a hinge.

            Since I have photo quota limits I can't post all the photos. But below is the usual slow motor springs, the longer one is for when Leslie issued motor stacks with a longer spring for the bottom rotor stack of like a 122/147 et al.

            The spring in your sidewinder T-412 looks like this:

              I've seen a many references to the "drum" type scanners for the T-series. My T-412 actually has a pie type scanner. It hasn't worked (at least - no vibrato) since I got the organ a few years ago; and since it's not at home, I haven't had the opportunity to try get it working. Since I successfully freed up the scanner on an M2, however, I have more confidence to dig into it.
              It is interesting that Hammond switched scanner types in the same model. I don't know the serial number of mine off hand, but I would assume mine is older than that one?

            Now the 205 is a rare bird to my eyes. First time to know of/see this unit.

            Don must've gone whole hog on the Rotosonic idea that he loved so much.

            The top rotor looks like this.

            The sound of the 205 is not as shimmering as the standard rotor sound as I think the moving speakers are covered by the housing that holds it so the sound waves are not allowed to scatter as much as a treble horn or normal bass rotor.

              It is interesting also, since my "other" organ is an R-124, for which the only Leslie recommended to pair with was the 610, which I understand was the "decorator" cabinet version of the 205. I have seen a few 610's on the market, but I will take Andyg's advice and stay away from that combination. I have toyed with the idea, however, of building some kind of horrific Roto-franken-leslie with the 6x9 speakers, and other parts from a gutted 705 that I bought in order to switch out the one speed lower motor on my 900 with a two speed...

            I know next to nothing about the back then popular model T-412. I played a Hammond BC during high school and later worked selling Lowrey organs up in San Francisco. I only came into knowing about this T model because I bought a rotor system off eBay to make a Vibratone replacing the original '60's Fender I had playing a Fender Contempo through it back in the '60's. Wanting to know what was the donor organ for the rotor system I now have and am working on putting a cabinet together for it, I came upon the T-412 photo above and got to see how the rotor was installed. The rotor system's wooden structure is exactly what I have and the logo/legend pasted into these rotor units are exactly the same.

              Some like the odd systems. And they tinker with them same as others tinker with the tried and true. Back as a teen I experimented with adding a hardware store motor to my Vibratone to see what going faster sounded like. Not good. Such is youth. I did wonder what the top rotor of the 205 would sound like sideways in a Vibratone cabinet.

                Sadly, it has been 20 years since my avatar picture; so I no longer have youth as an excuse.....
