    Thanks Lamar,

    Your description is very thorough, and makes perfect sense. There sure was a lot of inventiveness applied to mechanical sound animation back in the day. Of all the styles I have ever heard of / seen, this one is one I have never seen mentioned before this.
    Regards, Larry

    I think the flappers came about in the early 1900s, and the hooters came later. Either way, I think the restaurant is still in business.

    Seriously, I've never heard of, nor have ever seen the speaker style you shared. I've played at least three TC-? organs, and have never seen those speakers on any of them. One was very pipe-like sounding (live church), while the other was more dead (dry church). The third I only played once (Catholic church), and I think it was somewhere in-between. Ironically, the saving grace of each organ was Allen's Reeds on the TC series organs.

    Maybe I will have the opportunity to see that system live before I croak. Thank you for sharing the particulars on that speaker style.

    Allen used rotating paddles in front of Jensen horn drivers for reed channels in some of their custom speaker installations too. Here's a photo of the late, lamented Sacramento instrument, showing two horns with paddles and two without. The o-ring belt is missing between the motor and the paddle shafts.

    Hi, Larry. Thanks for the picture. (What was the Sacramento instrument?)

    I'll get a picture of the smaller gyro I have, too, (but I'm not planning to use it with the TC-4).

    I've ordered some small terminal strips that look very much like the ones Allen used that I want to add for the speakers in the gyro. There are filter caps inside, but no chokes.

    I tried the "reed chorus" out for an extended play yesterday, and it was sounding better to my ears by the time I stopped.

    And just planning and plotting, but this gyro doesn't have idle capability, so I could add a 14 VDC relay to activate it. And I could use a couple of the six unused antiphonal relay tabs on the organ to run the gyro and the flapper. (It won't need a Gyro Off tab.)

    I could borrow a relay from the '59, but I think a heavy duty one might be in order.

    Larry,

    Your photo explains quite a bit. If I am guessing correctly, the "paddles" are the same as the rotating paddles in a vibraphone which help distribute the sound of that instrument? If so, I now fully understand what they do and what they are. Thank you!

    Yes, the Allen rotating paddle system was just a small version of what is found on many other types of instruments to create a tremulant effect. Even Austin pipe organs with the Universal Wind Chest system used them since it was not possible to use a traditional tremulant system shaking the wind pressure.

    The very large 1962 analog Allen organ that was in Sacramento has been discussed several times before on this forum. Here's a video of it before it was removed: https://www.youtube.com/watch?v=LuVcJAGR4eI And here is a link to the photos: http://s862.photobucket.com/user/Del...962CustomAllen

    I have both AC motor (one speed) and DC motor (multiple speed) Allen gyro cabinets on my analog theater organ. I do like the multi-speed cabinets best but they do require the Allen DC control unit and special motor.

    So it's just a variant on the Vox Humana tremulant system on reed organs/pump organs. Interesting.

    Thank you, Larry. It may be old news around the forum, but it's new to me. Wow!

    Looks like it has the wood-sided white-topped keys like my '59. So now we've identified three types of keys - piano style, wood-sided plastic, pegged-insert plastic - that were used in the 50's to 60's.
