  • Connecting a T500 to a Leslie 351?

    I have an opportunity to acquire a T500 (specific model not know at this time) and have two Leslies, a 125 and 351. These have 6-pin connectors although the kits are wired differently and each speaker has it's own cable. The T500 has an internal Leslie but I prefer having an external speaker at times. For the T500, can the organ side of the connection be modified to accept a 6-pin connector?

    Not simply. You will have to source, or build, a suitable fitting kit for either of the two leslies. The 351 would sound much better than the 125, of course. You would only use the rotary channel of the 351, with no input to the second stationary amp, which could be disabled if you wish.

    The 125 would require a standard 26-1 kit. The 351 could use a modified, rewired 26-1 kit. I have a feeling you asked about that before.
    It's not what you play. It's not how you play. It's the fact that you're playing that counts.

      Hello andyg, my earlier question was about connecting two Leslies, a 125 and a 351, to the same L143 and this was resolved by using different connection kits, and cords, for each Leslie with no intention of having both plugged in at the same time. My question this time pertains to connecting a T500, which already has an 11 pin plug from the factory, to the 6 pin 351. The T500 has an internal Leslie but I like having an external one to go to frequently.

      Are you sure the T500 has a 11 pin?

    there's an interesting post here about the 351...
    https://organforum.com/forums/forum/...h-a-leslie-351

    I don't know anything about the 351 or the 125, but I believe a hookup kit can be made up between any organ and any leslie... from a brief glance at the above link it looks like a modification was required in the 351 for that hookup... but often a bit of modification is required in the T500 to hook it up to a regular leslie, since it's built to go with the two channel, solid state leslie 720.

    The T500 is originally wired to send the low bass to a separate channel, the mids and highs would then be split into horns and rotors... so for a regular leslie it would involve taking the signal from the T500 before the bass was taken off. That's not hard to suss out, there are a couple of crossovers near the organ's internal speakers.

    The solid state leslies used only 12V for the speed switching, so if your two leslies are tube powered then a new switching kit will be necessary to set up.

    A quick google tells me the125 is a drum-only leslie, so it won't be hugely different in character from the internal leslie (except less muffled by the organ body!)

    A quick look at Captain Foldback shows me the 351 has some similarities to the 251, though whether that's just the cabinet or the amp I don't know.
    He hasn't got the service manual for the 351 but the 251 is there and some of the other 300 series manuals ...

      Thank you, Brendon! I currently use the two different Leslies with the L143 I have and the T500 would be an upgrade in organs for me. Presently, I do prefer the L143 through the 351 and I don't use the Leslie at the same time.

        The same answer applies. Connect the T500 to the 351 as you connected the L143. You can take the full range organ signal from the green wire that goes from the amp up to the headphones socket.

        Brendon, the 251 and 351 share the same electronics, it's just the cabinet that's different.
