gyrophonic projector switch

[Guest]

I recently purchased an Allen Organ Co. Gyrophonic Projector (the larger on with 3 12", 3 tweeters, and 2 15" speakers). What I am trying to find out is how to wire a switch to it in order to turn the motor on and off (and fast and slow if possible). The motor is of the DC variety. On the back there is a 4 pin connection point with pins numbered 1, 2, 3, and 4. Seeing as how i wont be using this cabinet with an Allen organ a separate switch box is a must. Any help at all would be greatly appriciated as I can not seem to find any information on this problem anywhere.</p>

Thanks in advance for any help,</p>

(also i hope i posted this in the right place, if not point me there please and i will repost)</p>

Hi Rob,</p>

Those are some contraptions aren't they? I picked up an Allen Theatre Deluxe a few months ago to save it from the dump. It's got 4 speaker cabinets including two different gyro cabinets. As I recall one has a simple AC motor and the other a DC motor with a very rustic looking controller. I just love the design of this vintage stuff. Anyway I'll look at the cabinets to refresh myself on what connectors they have. I've also got some service documentation from Allen as well as some on-line docs so I'll check it to see what information they have on the gyro cabs.</p>

Do you know what specific model number that you have??</p>

I am not sure of the model number for the entire cabinet (the back cover is missing).</p>

Here is the model number off of the top of the motor: 5bc44ab1723a</p>

On the back in marker is Ju-572188</p>

Thanks again for the help,</p>

I have a Gyrophonic Projector that sounds identical to yours and need to figure out the same thing: how to switch the the motor on and off using the four pins. If you figure it out let me know. I'll do the same. Thanks.</p>

Re: gyrophonic projector switch



I have attempted to contact the service manager at Allen Organ Co. with no luck. My next step is going to be contacting thier parts department and seeing what they say (maybe the actuall rockers for the organ and the real cord will do the trick, if it doesn't cost to much).</p>

If i cant get the thing up and running soon i think i will either sell it (not even sure what it would be worth) or gut it, sell the speakers and try to make one heck of a rotation horn out of the pieces.</p>

On a side note, anyone know what these guys are worth, either as a whole or in parts (amp, speakers, power supply etc.)</p>

Thanks again,</p>

Hi All,</p>

I found the section in my Allen manual that covers the gyro connectors. It looks like there are a couple of different flavors covering gyro supplies with and without relays. I'll try and post something tomorrow (too late in the evening for that kind of work) that shows the switch control connections for the two types. Looks pretty simple.</p>

Great!. I look forward to some gyrophonic experimentation.

</p>

So this is my gyrophonic motor controller. We've found that if I supply the 14 vdc (I used a 12 vdc 2 amp power supply) I am able to turn the motor on and off and seem to have three speeds. The top pin of the 14 vdc (on my unit) is hot and connected directly to the top right hand pin of "switch". The bottom pin of the 14 vdc is ground and connected directly to the bottom left pin of "switch". Now if I jumper between the top right and the top left I get a very slow rotation. Top right jumpered to bottom right = a bit faster. Top right jumpered to both top left and bottom right = fastest. I don't know if I'm doing this right but it works. If anyone has any suggestions (or warnings) please let me know.

Hi Guys,</p>

Sorry to take so long but I was out of town. Here's a couple of pics showing the schematic and hookup of these units...</p>

Re: gyrophonic projector switch



sorry for the long delay with my reply, i have been on the road doing some music playing.</p>

first, congrats gyro on getting your speakers to turn.</p>

second, thanks tinker for posting the awesome schematics!!!!!!!</p>

unfortunately i don't read schematics very well however, i believe that what i am dealing with would more concern the bottom set (gyro power supply fig. 190 also fig. 188)
</p>

my power supply doesn't not have the 14 volt connection point on it.</p>

i have tried every possible connection pattern using a dual pole, dual throw switch, as well as using 2 single throw, single pole switches. i also tried just plain connecting the pins with jumpers using every possible patter. neither of these did me any good.</p>

what i am lead to believe is that i need power going through 2 of the pins (+ x volts d.c. and ground?) then using a switch (or jumpers) i connect pins 2, 3, or 4 to pin 1 in order to get different speeds and off.</p>

if this is a correct assumption (not sure it is) then where do i get the power from? did it come through the connection from the organ? will i need another power supply? </p>

once again i really appriciate the help as i would love to get this thing working rather than the other, less enjoyable options (like gutting it and building smaller cabinets for the speakers, or selling it for parts)</p>

Re: gyrophonic projector switch



sorry for the self bump but i have tried a few things that may be relevent.</p>

i took a 14v 1.2amp DC power supply and hooked it up like the schematic says. (i still dont know if this is a good idea but since i dont have the 14 v plug on my model im not sure what other way to test this)</p>

with the ground on pin one, when i hook the hot up to pin 2 or 3 i here something click on, but it seems to be coming from the power supply section of the cabinet and not the motor.</p>

the motor still does nothing, though the hum does get louder or softer depending on which pin i hook the hot wire up to. does this mean that the motor is dead? or am i still doing something wrong? </p>

also does anyone know of a way to test the motor? all of this could be a waste of time if the motor itself does not work.
</p>

on a side not i am picking up a digital camera tomorrow and will post up some shots of this monster. </p>

thanks again,</p>

Re: gyrophonic projector switch



So when I removed the metal cover that was covering the two relays (switches) behind the huge brown resistor (you can see the uncovered relays in the picture in my earlier post), I discovered that if I pressed the tops of either relay it caused the motor to turn. Both press down caused the fastest rotation. Of course the AC power had to be supplied and the motor had to be plugged into the controller first as I realized when nothing happened at first. I then messed with the 14 volt stuff and discovered a clicking noise similar to what you describe that was from the relays contacting (doing the same thing that pushing them down did). If you press down the relays (assuming your unit is similar to mine in that regard) you may get some rotation. If it doesn't work it doesn't necessarliy mean your motor is bad. I don't know how to test the motor unfortunately; but you might try making sure that the relays are actually doing their job by bypassing one or both.

thanks for the tip.</p>

i havent really messed with it since my last post, but i will give this a try if i can later today.</p>

lets hope it works.</p>

Hey
I just wanted to say thanks for the schematic and description below it.
I have the 3x3 DC drive and was able to get it working.May get the lager speaker one also.

Have a good one
