    Leslie problem on Wurlitzer 630T

    Hello,
    I'm new on this site. I'm french. Sorry for my bad english. If you speak french, please, give me your response in french.
    I just bought a marvelous Wurlitzer 630T. It seems that it just came out of the store.



    however However, a failure has occurred. when I stop the leslie, the rotor continues to turn at low speeds and a new low-noise rotation (most troublesome that during operation) appears (clock ... clock ... clock ...)
    I spent the hand behind the panel speaker and I felt a wheel axle coming out. I pressed it with my finger very easily. After that, it worked, but this axis takes this position and dysfunction returns.
    Can I remove the wood panel without the risk of not being able to go back?
    Do you have plans and diagrams in this model leslie?
    Please, help me. I do not know anyone who can repair this outage in France.

    Thanks to all.

    I have moved this to the proper section - Home Organs.

    Forum posts should be in English please, but if anyone wishes to translate their reply into French and post in both languages, that would be OK in this case.

    The slow rotation of the rotor is normal. It gives the sound a bit of movement and life. You may remove the wood panel with little risk that it cannot go back on. Just keep track of where the screws go if they are not identical. Perhaps you can find a mechanically skilled friend that can devise a fake "finger" to keep that axle in place. They do not need to know organs, just mechanics.

    Another forum member may can give you a parts source (in the USA probably) where you could purchase a new Spectratone (Wurtlitzer's "Leslie"?) drive.

      Emanon, according to the Organ Blue Book, your 630T has a REAL, live two-speed Leslie, not the Spectratone imitation used in many earlier Wurlitzers. Most inbuilt Leslie units have a paper sheet attached to the black panel of the unit. That gives you some
      basic maintenance information: send me a Private Message (also known as a PM) and I can send you more info.

      What part of France are you in? My ancestors came to America from Besancon, FR.

        Hi,
        thank you for this reply, Kurzweil. Unfortunately i have a new problem much more serious, there has been an explosive flame in the organ and my electrical system has tripped. The instrument does not work. This smells of burning. Since I tried the organ it was a loud buzzing sometimes mixed with some kind of tear reminiscent of deficient electrical components. Despite this, he was walking and I could fully enjoy the sounds of the organ. I hope this is not too serious. Before I bought it, it had not been used for at least two years, is that it could be dry capacitors that have burned? The organ is shorted, if one tries to restore power, electrical circuit breaker trips again.
        I do not know what to do.

        Thanks for your suggestions

          I'm near near Lapalisse (03), Allier, approximately three-hour drive from Besançon.
          Ok for a PM.

          Thank you

            Check the Organ's power cord for chew marks (from mice) or breaks in the wire insulation. it sounds like you have a short circuit. there are several fuses in the 630 that have probably blown too so you will need to replace them but they are inexpensive. i have the 630 owners manual if you need any info.

            what voltage do you have in France? MAKE SURE THE ORGAN IS COMPATIBLE WITH THAT VOLTAGE. in mid 1970's europe voltage varied from some areas and the Wurlitzer may not be compatible. the info should be on the back panel

              Very likely, what with the age of the instrument. Other replies in this thread come from those more active with these older instruments so check the simple things like the power cord and voltage first. Since it played for a while, I am thinking "power capacitor" or two.

                Hello,
                after removal of power and amplification elements, I discovered that this is the second amplifier transformer that burned. What can be the cause? what can be the repercussions on other components of the organ?

                  did you check to see if the voltage is compatible? wurlitzers amps are pretty reliable so i think you either fed it to much voltage or you have a short caused by bad wire insulation by animal or by a cord rubbing a sharp metal edge. wurlitzer power cords of this age were pretty durable.

                    Transformers are generally victims, rather than causes. I still vote power capacitor. Of course obtaining a replacement will be required before going to the trouble of replacing other components, as the transformer is not as common.
