Rotating Speaker!

[Lonely Raven]

So I just stumbled into this setup. I can still get the organ it came from, but it was a transistor organ, I'm guessing from the '70s.

What can I do with this?

Eminence plug alnico speakers I think. Does it still work?

Could make a nice Leslie type setup for a custom chassis! If you have the amp schematic you could do it over with tubes instead of sand. Would likely sound really good especially with a couple of old 6V6GT/Gs. Maybe even a quad, but I don't think those speakers would like a pair of 6550s like the old Leslies, too much power.

I have nothing but what you see. It was "in storage for a long time and we aren't sure if it works". A church up the road was hauling it to the curb...I saw the back of the rotating cabinet and said "here, I'll help you with that" right into my wagon.

The organ has a bunch of vintage caps and resistors, but I'm not sure it's worth trying to gut right there in the parking lot.

As for the speakers...I assume they work, but I don't know anything about the amps...it looks like they had some funky connector between the organ and the speaker.

I should be able to power the motor and drive the speakers with just a tweed deluxe or something, right?

Is it safe to say the transformer in the 2X15 cab is probably some sort of output transformer?

The caps and organ parts are probably a loss.

The transformer in the cab is the OT for the organ(or house system)

the leslie looking cab has a power amp so you would need to give it a preamp. if you disconnect the power amp yes an amp will more the speakers. observe the ohm load for safe use.

The whirly thang is an Allen Gyrophonic speaker. Looks identical to the one I parted out. The 8 inchers that were in mine are CTS, and they work really well in a Champ if the OT used is something other than stock to match with their 8 ohm rating. Your larger speakers in the gyro cab have the CTS square magnets, but I'm not sure that they are 8's like mine were... Mine sound bigger than they look to deserve to. I stilll have the tweeters, have not used them for anything. The big cab with the eminience 15's I also have, I took the 15's out of it, they did a good clean tone but the OD was not articulate at all, very mushy. Those speakers wiere very tired, the spiders were not flat anymore. So I took a skilsaw, cut the back off all the way around to get a now shortened 12 inch depth from the baffle to the back, used the two long pieces along with some scrap wood for cleats to make back baffles, trimmed with that same skil worm drive, ending up with a 4 inch slot width the whole cab length, stuck in a pair of JBL g135's, and presto, a seriously monster sounding 16 ohm guitar cab that does nice cleans and OD, huge sounding and very efficient.

I'm pretty sure my spinning cab is loaded with 12", and the fixed cab is definitely 15".

I did some searching and found the same name you posted Mav.

I also found that the power supply for the rotating portion of the speaker needs 120v to turn, and 14 volts to click relays that set the speed according to the giant adjustable resistors on the top of the power supply.

I'm going to try and see if I can get the cabinet to turn, then see about adjusting speed, then worry about how it sounds. Once I can setup a method for making it turn as I wish, I'll get some light weight guitar oriented speaker in there, maybe some inexpensive Weber Neos or WGS ceramics.

It will be a fun, long term project. I'm in no hurry to figure this out, so any info or suggestions are welcomed.

Thanks for the info so far!

That's pretty cool!

What does the front of the baffle for the spinning speakers look like?

[212Mavguy]

I think the stock speakers will sound surprisingly good for guitar...

Does it rotate? I got a couple old Leslie cabs two years ago and they were really fun to play through. I couldn't justify the space in the apt we lived in so I sold them. Really good score though

It's got some ragged light weight speaker grill material that looks like it's dry rotted away. The cabinet is just (vintage!) plywood. From the front it looks like it's cobbled in someones garage from scrap.

I don't know if it turns yet. The church I got it from had it in storage for years, and they really didn't know anything about it. I've been too busy to do anything besides push it into the garage for another day....I really need to clean out my garage so I can work on other projects, I'm taking home too many strays lately!
