@brandonelliot The hardest part would be finding the two speed motor assemblies. There are two outlets for the motors. The once closest to the rear is controled by the toggle switch on the side of the cabinet. You would have to wire that into the plate relay and use that outlet for the slow motors. Thanks for watching.
I watched your videos backwards. Nice repair job and it sounds just fine. Depending on the speaker magnet design, I have had some luck in realigning rubbing voice coils either by bending the magnet assembly a little or tapping it with a hammper to slightly move the magnet. to get it centered. If it rubs a lot I wouldn't play it much as it will eventually short out the voice coil.
@tonewheelplayer It is nice to have that slow rotation for the chorale effect. I used that many times whan I played out pro on a B-3 with 122 Leslie. Thanks again for watching. Gary
@HD7100 I think it would be a good idea to have the original field coil reconed. I have heard they have a better bass response due to the strong even magnetic field generated by the field coil.
@AllAmericanFiveRadio Thanks Rick. I am posting my next radio restoration project. I say so many "ums and ers" in it that it drives ME crazy. I wish I had that wonderful voice and educator style that you have. Thanks for watching and commenting. Gary
Nice job! :) Something to point out: this Leslie may have been modified more than you realize. The original Jensen U-20 loudspeaker was replaced with the more common V-21. Also the rectifiers originally were the older (hard to find) 4-pin 5Z3's, and the amp was modified to handle the 5U4's. I used to have a 31H and loved it. :) I modified it to handle 2-speed motors; a nice improvement in my opinion.
@tonewheelplayer Another modification was the relay/motor controls. The original 31H didn't allow for console switching. The 3 plugs on the side of the amp were for the single-speed motors; two of which were controlled by the switch on the side of the cabinet, the other was always on. It was popular for a while to leave the bass rotor running at full speed and only turn on/off the upper horn, hence the multiple-choice motor sockets.
Vibratone was the initial name. But before it just became Leslie it was Leslie Vibratone. If you look at the little back plate on this video it says Leslie Vibratone. I wasn’t around in the 40s/50s lol but I’m pretty sure everyone just called them Leslie’s :)
@maynardcat The bass speaker is an electrodynamic. It should be reconed. The other option would be to elliminate the field coil from the circuit and install a 15" PM bass speaker with a 16 ohm voice coil. I bought the speaker to give to a friend but it is so rough I'm not sure if this speaker is the right one for him. Leslie cabinets are hard to find these days. Gary
Very interesting forensic history. Very nice project and fix.
So amazing. That switch on the side caught me off guard.

Only the V30 was referred to as a the Vibratone. From the 31A forward all models were referred to as "Leslie".

@CindyBradyTooh Thanks for watching. I have more interesting stuff to post that will be appearing on my channel now and then.
@karlmahlmann It's good to keep some of the old technology operating and the old Hammonds still sound good to me. Gary
well done
