    Problems with Leslie 122 Converted to Jack plug

    Hi!
    I have a problem with my leslie 122.
    I took it to a technician who modified it to use a jack.
    The technician coupled in the back cover a transformer 220v to 110v (I am in Spain), a new relays and a connector jack.
    All this is connected to the amplifier with a 6-pin connector. Then, I plug the leslie into the electric current and I plug the
    hammond with the jack. But the sound is broken ... even though the amp is 3.
    Why could be this happening??
    The technician does not help me ....
    I can send photos.
    Thanks!
    A greeting!!!

    What kind of jack? Is it a three wire balanced jack?

    No, It's a mono jack.
    The technician put the transformer 220V-110V. However, the leslie indicates 120V. Could this fact be related to the problem?
    Thanks!

    No, the mains voltage is not your problem.

    But does your technician understand that the 122 needs balanced input signal? Has he installed a small audio transformer into it as well (in addition to the mains transformer)?

    what he said, how are you boosting the signal as well?

    You want a 147

    and Korg KRONOS X73
    Looking for that mythical cheap or free A, BV, CV, C2, C3 or A100 but wouldn't say no to a free B3

    I see a mono female connector for audio.
    To the 6-pin connector go directly:
    -The black and red wires of the jack
    -The blue and gray wires of the transformer
    -And a yellow cable connected to the black cable of the jack
    There is no audio transformer

    Thanks!!

    Which pins (they are numbered) do the red, black and yellow go to, respectively?

    It appears your technician does not know how a Leslie 122 is wired, or what kind of signal it expects.

    Hola

    Certainly the connection must be symmetrical.
    But, I do not understand how do you do to change the speed of the leslie.

    Can you explain or send some pictures.

    I'm not in spain ...
