Title says it all. Any help is appreciated. Thanks,

That a Wurlitzer 750. Oops!

I know the older ones like my 1936 Wurlitzer 412 do not work well on free play because they'll just keep playing records without stopping. The newer ones like my 1957 Wurlitzer 2150 are easy to put on free play with no danger of the latch solenoid overheating like on the Seeburgs, but your 750 is somewhere in the middle and I have no answer. The guys over at Jukebox-list will surely know:

Go see Ron over at www.phonoland.com - he'd know, he's the Juke Guru there and highly regarded by me and many.

The tip above on Ron Rich is excellent. He is a great guy and very helpful.

That being said, the easiest and safest way I've found to put a juke into free play is to wire a door bell switch to the coin mechanism switches. This makes it typically act the same as if a coin was dropped in. One push, one play or however many plays that coin slot is set up for. The switch can be mounted wherever it's convenient or even hidden, as long as you can reach it.

Many times, someone will just make the latch selenoid active all the time as mentioned above. Especially with Seeburgs because it's easy to do. Not a good idea unless you want to burn it up and possibly start a fire. I've had three Seeburgs that were like this. I converted them all to the door bell switch. Latch selenoids were only designed to remain active until the selections were made, then disengage until more coins were dropped in.

The Wurlitzer was manufactured with a electrical selector, Model 750-E (bicycle chain to selection coil drum) and also as a mechanical select jukebox Model 750-M (same mechanism as a Model 700 etc.).

I have two 750-E machines. They are both on freeplay. I adjusted the Accumulator switchblades to always have credit. Page 40 - "Play Registering Circuit" of my manual has an explanation of the workings. If your machine is a 750-E there should be a green window that lights when credit is established on the title board. Mine stay lit all the time once I adjusted the accumulator for free play.

I have a Wurlitzer 800 with mechanical selector. I am sure it is the same as the 750-M. I installed a switch on the coin return button to provide credit. Each button push is one credit. Selections must be made before establishing credit or the mechanism will (should) play the next selection following the last selection 23/24 of a revolution. I wired the pushbutton to the accumulator.

The jukeboxlist is a good place for help from knowlegable people unlike me who just wanders around in the jukebox world.

It is good to have a manual to help get everything going.

No response to my post to Ron over at www.phonoland.com after several days. On http://lists.netlojix.com/mailman/listinfo/jukebox-list, I got a bazillion emails of others questions, but the moderator would not post my question. Sounds like juke47 has a handle on this. I'll try it. Thanks Juke!

Well, I have the manual but dont see the accumulator switch blades anywhere on the cabinet wiring diagram for the 750E. Where does it tell me where the accumulator switch blades are? Thanks!

Hi,
I restored my 750's some years ago so I just don't remember exactly how I put them on freeplay. I remember studying the manual and making a change in the accumulator. The ratchet wheels add/subtract credit so I think I added credit to the wheel and then defeated the removal of credit. I will assume yours is a 750-E and not a 750-M. Pictures show the green credit window in a 750-E title board. The M model did not have credit window that because as soon as a coin was deposited the mechanism went looking for the selection. Anyway pics show the areas in the manual to take a look at. Different versions of the manuals will likely have different pages. These things are just a hobby and I have a lousy memory. I'll try to spend some time figuring out what I did for freeplay.

Thanks for taking the time for putting together such a detailed response. I'm afraid I have a ways to go to get this box working. I keep finding obvious problems like a loose ratchet wheel on the selector board, etc. So far, the motor runs and the turntable turns, but no action from the selector nor the mechanism that raises and lowers the selected tray. Occasionally, it will get in the mode of continuous cycling of extending a tray raising the turntable them immediately lowering it, repeating over and over again with no change in the selected tray. The selections are not getting to the selection wheel that is chain driven. I'm going to have to take the time to understand how this box works (juke 101) and unfortunately, the manual gives a lot of details but no top down description of how it works. I searched for expert help in the Denver area to no avail, so I'll just have to take the time to figure it out. Best,
Dave

I own three Seeburgs. I have one of them with free play. Like Juke47, I wired a push button switch into the coin return button's linkage. I also have a toggle switch in series with the push button switch. With the toggle switch, I can select between coin only (no free play), one push to equal a nickel, or one push to equal a quarter. In effect, the push button shorts the coin switch that is selected by the toggle switch. When activated, I push the coin return to get free plays. Coins still work with free play activated, too.

When I get a 24 select Wurlitzer I always clean the mechanism as best I can. This is how I do it.

I remove everything electrical and the small brake band. I remove the wood mechanism board. I take the mechanism to the backyard and fill a squirt bottle with 50% sudsy ammonia and 50% - 409 cleaner. I spray it like crazy and use a toothbrush to scrub it. I try to be careful of the ammonia fumes even though I am outdoors. I hose the whole thing and go back for places I have missed. After the last hosing I blow it dry with air. I then, right away, use a fair amount of 20wt non detergent oil to lube everything that moves in operation. I have been using Mobil 1 synthetic. I then allow it all to bake in the warm Arizona sun for the rest of the day.

I later always take the record tray stack apart for cleaning, lubrication and polishing. Just keep track of where the washers and spacers go. I run it through several cycles by hand; it gets tiresome turning the shaft. I oil it some more on rotating element shafts. There is a brass clutch next to the large fiber gear. It must be very free to slide back and forth with good lubrication.

I watch very carefully for correct tray take-out adjustment. Worn mechanisms or poorly adjusted mechanisms often pull two trays out at the same time. When the turntable rises it will strike the trays. The resultant jam strains everything and can strip the fiber gear. A pain to replace and also $$. I have added an inline fuse to several of my Wurlitzer jukebox motors with a low amp fuse. I hope the fuse will blow before the fiber gear strips.
