Looks like I can take the backs off if the 375's are out of the way and won't have to disturb the horns. If I take off the 4 acorn nuts that hold the driver to the horn is there any kind of gasket or "o" ring to watch out for? Is this the correct way to take them apart? I want to get good pics and all the SN's before they go to evilbay.
Really hope someone will get them and keep them as they are, kinda an homage to the guy who went to the trouble to put them together, and they sound great as is. Also they are in a pretty good package for shipping. Steve I'll take your advice and try the "Best Offer" method.
I'm guessing anyone who hangs out here regular has probably already seen them but I'll put a link in the for sale forum.
Guess I'll just keep the C40's and after these sell buy a set of "modern" JBL's with a little smaller footprint.
My Thanks for all the replies and help. Mike (even a blind hog finds an acorn once in awhile)
I recently picked up a pair of similar cabinets, although the upper space used by the filter/crossover in this one had been modified/built? to accomodate a short length fflourescent light fixture pointing upwards with a white fogged glass top lense, making the speaker enclosure a top lit pedastal. The grills slid into the frame from the bottom, concealing a 15" Isophon round driver and a horn assembly with a midrange and two tweeters mounted in the sides of the horn throat pointed outwards. Speakers apparantly came from circa 1959-63 vintage, but play very smoothly.
the Isophon (German) P38/45/10 woofer although only 1-1/2" voice coil still is spec'ed at 146,000 Maxwells total flux with 10,000 Gauss in the air gap. Free resonance of 40 Hz, and the cabinet is ported at the bottom but well sealed thoughout. Baffle is only attached by 6 screws simply spanning the enclosure and the port is simply a rectangular slot cut in the baffle, so might be easily modified.
I was curious, was this top compartment a typical cabinet design feature in earlier speaker enclosures? I've seen it in a handful of cabinets, but curious if it was name brand specific or a generic home built simple design feature, say for a turntable at one time?
The cabinet is a Hammond Organ JR-20, or HR-20 tone cabinet. My father was a Hammond Organ Factory Artist, and sold organs and pianos for 40 years until his death at the age of 57. He was very well known in Moline, Illinois and the Quad Cities as a nightclub entertainer, and also here in Alaska.
I was taught as a little boy to help dad move and repair organs and leslie speakers. I still do.
I have all of the Hammond service manuals back to the B models of the 40's.
The Hammond tone cabinet uses a 12" alnico speaker pointing up for the reverb channel with a separate 15 watt amp. It uses a 20 watt amp fullrange to two 15" speakers.
I have one PR-40 tone cabinet in storage that are always available, because organ-grinders want a 122 or 147 Lelie with the rotating snowcone horns on a 1" compression driver for the tremolo effect! Only Baptist and Methodist churches want the Pr-40 tone cabinets. It gives that real "churchy" sound.
If you find an older leslie, grab it! They are very sought after especially the 50 watt tube amp with TungSol 6550's.
Now I'm thinking of strapping some old JBL's in it and selling it for BIG BUCKS to some moron on the bay.

Hi Scott, hey maybe you can lend some insight into this
Leslie. I've had it for a while...it works fine, it's got what I thought
was a 16" field coil speaker in it. It's the Model 21H and I believe it
to be built in 1952. Is it worth anything?

Thanks in advance!
I've seen at least three of those old organ speaker cabinets at estate sales in recent years. I never pay much attention, as I always figure that they would cost more to ship them than their value.
Dear SteveMac,
Check out this link.

Yes, I believe a model 21h is worthy, because of its smaller size, and can easily accept a 122 or 147 amp. A powerful, potent package that can used used with a Leslie Combo organ preamp, and be plugged into a huge variety of keyboards looking for a REAL Leslie sound!!!!
Scott.
The leslie in question used a Jensen 15" permanant magnet speaker, an 800hz crossover to a 1" compression driver!
Perfectly matched to a M100 Hammond Spinet organ, also known as a "baby B3."
Scott.
The cabs are Hammond HR40s, and were sold mostly with late '50s Hammond console organs like the B and C series that had no internal power amp or speakers. Original components included 9x Jensen 10s, 2x Jensen 12s, a 3 channel active crossover tube biamp (4x6V6 for <200Hz bass, 2x6V6 for >200Hz reverb channel, 2 more for non-reverb channel), and Hammond's oil-filled reverb unit, which I believe was the first production spring reverb. I've got 5 of them, only 3 left to restore.
One of several innovations of the stock cabs was the open back design which permitted tuning the enclosure to the room by varying the distance from the wall behind it. When setup right, those 9 10" Jensens produce bass that puts all but the hot-rodded Leslies to shame.
Here's a shot from the rear, I'll post more if there's interest.
Hi Mike,
Those are rare and valuable horns as well.
And like Steve said these speakers that combine the JBL made and AMPEX made components are very rare.
Please add their serial numbers to the serial number thread!
By the way, those "cut corners" labels on the woofers visible in one of your pictures usually have a "date code" serial number that can reveal when they were originally made.
Can you get a close up picture of the labels, or tell us the serial numbers on the cut corners labels?
Fantastic find!
Cream and Tull through a tube amp on these babies must be heaven,
congrats on your score!

209-236 The 209 is correct, odd it would be exactly 100 off and still
in sequence

309-238
309-241
Thank you Scott. Very nice link.
Funny, no pictures or storyline on the field coil speaker.
I'm laughing right now because I should know this as I cleaned
the cabinet once and had the speaker in my face but for the
life of me, I don't remember. again, thanks..
