  • Mode T582 has no sound



    Dear Forum Members,</p>

    I am writing on behalf of a friend who just got a Hammond Model T582. He transported the organ apx. 25 miles and unloaded into his garage. The organ played fine prior to transporting the organ. A quick test after off loading produced normal function (according to him.). Now, a day later it make no sounds at all... not a thing! I tested drawbars, presets, and the rhythm bar. Nothing produces any sound. I took the back off and checked the fuse, it is fine. The power on lamp is on. Will you please share with me a few things that he and I can check for that may be an obvious" fix to this problem? I would be most appreciative. Tomorrow I am going to his place after work and it would be great if I a couple of things for us to look at together. Assume I know nothing about an organ, because I don't.... and neither does he. This will be a first "fix-it" for us both. Also, is this a tonewheel organ?</p>

    Thanks to you all, Jerry.

    Hi Jerry!</p>

    I've had the same thing happen a dozen times, it'll be ONE thing disconnected somewhere.... of course, I'm in there knocking things around all the time. It's not the organ's fault.</p>

    Firstly, there are actually 3 fuses to check, in case you didn't look at all three.</p>

    Also check every board to see if a connector has come off a pin, or even a wire sitting loose.</p>

    On the recovery board ( the one marked 124-000014) there are two trim knobs, one of these controls the volume out from the preamp. Put a mark on both knobs before you move them... so you know where to put them back to!</p>

    Try those first.</p>

    Cheers!</p>

      Oh, and yes, it's a tonewheel. It has a lot of filter circuitry which disguises that, though. </p>

      Modding it's become my most enjoyable hobby!</p>

      I'll be back shortly with an address for the Service Manual....</p>

      Actually, here it is.</p>

        Could be dirty tab contacts too, Have you tried presets as well as drawbars?Iremember mine were intermittent to start with.</P>


        Brendon isn't there an issue with the rhythem section on those that can render the organ into silence?</P>


        Cheers</P>

          Hiya Dave!</p>

          There is that, when the plug is pulled out of the drum machine (without a dummy plug wired up) the lower manual is lost, but it doesn't affect the whole organ.</p>

          Cheers!</p>

            You said no sound at all... Is the generator turning? If it's stuck there will be no sound.</P>


            Just a hunch...</P>

              Doh. I didn't even think of that.</p>

              When getting an organ home, first thing to do is apply hammond oil to the Tone Generator!</p>

              If it has become stuck, don't worry, the oiling will fix it.</p>

              Hammond oil is the stuff to use because it won't gum up the wicks in the TG. (you might already know that, of course!)</p>

              There are a couple of alternatives, but you're not likely to have them on hand anyhow. </p>

              Cheers</p>
