  • Wurlitzer 555 Funmaker with Orbit 3 - disassembly?

    Our son (somewhat of a technical wiz) has acquired a Wurlitzer 555 and has already fixed the foot pedals.
    We have been trying to access the insides/rear of the switches on the left for the middle keyboard because he thinks the Hawaiian Guitar sound is constantly running.

    Might someone have a manual for this organ?
    Might someone have diagrams or instructions for disassembling the organ?
    Might someone have advice for a remedy for the constant Hawaiian Guitar?
    Thank you in advance.

    Contact Morelock's Organ Parts and Services in Rienzi, Mississippi. They have all the Wurlitzer organ parts. They are very helpful as well.

      Thank you for the response, you795a. It's unclear at this point what part(s) are defective. Perhaps they can diagnose our problem better than we are able to describe it.

        They are very knowledgeable. They have the service manuals as well as all the parts. They helped me out several times.

          Diagnosing at a distance is almost impossible, other than for some very obvious faults. Depends on the make, model and fault, of course!

          Many, perhaps most, service manuals don't have disassembly instructions. What you'll have to do is look at all the screws and bolts that are located under the keybed, above the speakercloth. When you undo the correct ones, you'll usually find that the keyboards will hinge upwards. You'll have to remove the top lid first. This may slide off or hinge up, and is usually held in place by no more than a couple of screws. Finding them can be fun as makers tended to hide them for cosmetic reasons.
          It's not what you play. It's not how you play. It's the fact that you're playing that counts.

            Thank you, andyg. We discovered the hinge design only after we had removed several other screws!... oh, well...
            We can access the insides much easier now, but the circuit boards and wiring are beyond me.

            Might anyone know how to reestablish and/or stop the production of a certain sound setting - in this case the Hawaiian Guitar? It seems to be there all the time, underlying every other sound setting.

              If the Hawaiian Guitar voice is on at all times, even though its rocker tablet is in the off position, then it suggests that the first thing to investigate would be a problem with the contacts on that tablet. Second would be in the circuitry controlled by that tablet.
