  • Major Damage on 1950 C-2

    Hey everybody,

    I just started my restoration project on my 1950 C-2 and I think I discovered some major damage.

    The left part of the resistor panel has broken off. When I opened the organ, it was hanging there by the wire wound around the bottom of the field coil.

    Since then, that piece has completely broken off.

    Has anyone encountered this problem? And if so, how did you fix it?

    You can see the situation in the pictures I’ve attached.

    Mike,

    Good post. In 2013, I bought a 1955 B3, and took this picture a short time thereafter. This prompts me to want to note which wires go where, in case a solder joint breaks, and I do the wrong thing. Fortunately, everything works. So I have done nothing. Hope someone in the know comments!

      Dave,

      When I first brought the organ home, it fired up nicely. No problems. But it was running, I now know, while that piece of the resistor panel was dangling. Now that that piece has broken off, I’m wondering if this is something that cannot be replaced. I hope not!

        No question it can be replaced! The wiring diagrams are all available, and there should be even better components than original. If you take better high resolution photos and wiring diagram into a TV repair shop, you might get help there. If so, you can undo the two screws, desolder the 3 or 4 wires, and take it in. But make sure that the organ is unplugged!

        On the other hand, you might have a Hammond guru tech not far away from you, and it would be worth a hogsuecall....

        Here is a shot of an intact panel:

          Hi Mike -
          Yes ! I had the exact same damage to my C-3. Fortunately, none of the wiring was damaged; it was functioning fine. I simply put it back together with Super Glue.
          No more problem with it. That repair was years ago. The only down-side to my fix was that if anyone wants to remove it in the future, it may be a problem to get it off of the metal without damaging or ruining it. Even so, similar terminal strips are readily available, and if the coil wire is broken, it can also be re-soldered.

            Roger,

            Thanks for that reassurance. Do you mean I can find a terminal strip configured similarly to the resistor panel, or do you mean I can find a terminal strip that is not configured the same way but will work for this application?

            Either way, do you know a good place to get this kind of thing from?

            Thanks again!

              That part is just a couple coils of wire and a resistor. As long as the wires are connected, the fact that the plastic part is broken is really irellevant, as the plastic is just a means for mounting. As Roger said, you can just glue it together and it will work fine.

              I am pretty sure I have one of these out in the shop...if you want it let me know.

                Hey Bob!

                I’ll send you a private message to arrange for that part.

                Thanks!

                  I might have one of those. I'll have a look.

                    This is 1 inductor and a number of resistors. Some are carbon comp resistors, others are turns of green resistance wire. Their job is to convert the 4 outputs of the pedal switch assembly bus bars to two different mixtures of harmonics, which are then fed to the two pedal drawbars.

                    Their wiring is documented on the B2 / C2 wiring diagram, and it includes mention of wire colors.

                    I'm saying this because it's only critical to fix it if bass pedals are actually being played. If they're always removed, or this is a chop, it's a non-issue. Also it's good to understand what those components are for.

                      Muckelroy,

                      Your information is exccedingly helpful. So glad to hear from you.

                      With this information in mind, maybe we should call it the pedal resistor panel from now on? Haha

                        I think the official term (as per the factory service manual) is "pedal filter".
