My Mexican Sonata

[mexnielsen]

Wurlitzer 1050 Nostalgia, Mexican Sonata, just finished repairs, now just getting used to the site, more to come if this works

[mexnielsen]

Work is underway on my 49-year-old jukebox, Wurlitzer model 1050 Nostalgia, it was assembled in Mexico in 1973 and was named Sonata, it has in its time played approx. 139000 tunes 45 rpm singles, I change electronic components and repair worn mechanical parts and adjust it all as close to the original as possible. Such work requires patience and approach to Rum, Coca Cola and ice. The bar has been converted into a jukebox workshop. I have approx. 500 45 rpm discs waiting to be played.

Dear Mexnielsen,
Well whut kan one say-- ??
1. It's not a "WurliTzer", it is a "Sonata", which was the Mexican company that purchased the remaining parts for these from WurliTzer after they closed their plant in the USA. Depending upon when in that production run yours was built-- the "quality" went straight down hill !
2. In My Humble Opinion, when working on these you need MORE rum, in that glass, with just a splash of Coke ! Ron (hic-cup) Rich

Dear Ron Rich
Point 1 and 2 you are totally right about this, I found out that strong cups of coffee are better . I have it working though, now waiting for rubber grommets and drive belts for the record player motor, after that I will decide if a new cartridge will be needed. Will post more whem time allows

I cleaned the inside before beginning taking it all apart, a lot of dust everywhere. then onto the record magazine

Cleaned it all with soapy water and then all the labels with alcohol, the curled up ends I glued back with Crazy glue

Some of the dividers were out of line, I took them out and with a small file worked the base contact points until even

And here in again

 

I cleaned it all where possible with alcohol and 3M cleaning pads

Hi Mexnielsen,
I do not think "crazy glue" will hold very long on paper/plastic combinations such as that-- I would use a good "contact cement" -- Other wise-- looking good !! Ron Rich

[mexnielsen]

Hi Ron
I am aware of that Ron, Contact cement is more difficult to work with and normally get visible, if the labels start to come off again I will get new ones printed, but it will be a PIB job to change them, not to speak of the cost

Hi Mexnielsen,
That depends on how it's applied. To prevent the 'showing' when used with a paper product, I just put a very tin layer on the hard ( in this case, plastic ) part- and attach the paper side while it's still wet-- In this case, since it's plastic, I think one could use Testors Model Aeroplane Cement ??

I went on and changed all mini switches, I checked the old ones with an Ohm meter, nearly all of them showed differences from 0.2 to open circuit when switching and everything in between

I changed them with this type, where needed I used the actuator from the old ones, I could pry the new ones a little open to do that

Then onto the selection accumulator unit, I took it apart to get at the contact plates and contact blades for cleaning using alcohol and 3M cleaning pads, then onto all the latch pins, some of them was slightly bent so I carefully bent them back and checked every single one for free movement and function., cleaned all the rest and applied oil where needed using a SAE 20 motor oil, assembled the unit and was ready to check function and adjustments.

At this point I got the idea to start taking some photos and save them, thats why there are no pics from "before"

Checking function and adjustment according to manual I found this

The plunger for the left cancel magnet stayed down, it was totally bent, thats why some of the latch pins was bent disassemble again, got the plunger out and tried to straighten it, no such luck, it broke in two

I found a piece of steel plate in my workshop 1 mm thick as the plunger, used the other plunger to mark the plate, cut it out crudely with a Dremel, and then formed it with a fine file, after some tries and fine filing it came out good

Assembled it all again and next on readout switches

Hola Soren,

Glad to see you are working on your Sonata with your #1 tool, a Cuba!

New to this site, I haven't quite figured out how to properly respond, but perhaps this is a beginning.

[mexnielsen]

Welcome Jeff

You found me, I hope the Seeburg section will be interesting for you, Ron Rich is our guru like Martin in Beoworld. To post images I use postimages.org/

I got busy otherwise, but lets go on here, to check and adjust the readout switches I used my Ohm meter and they were OK, apparently these mini switches are better quality than the other switch types (where I had to change all of them) I checked both sides carefully and several times NO and NC. To adjust them the magazine has to be attached so I had to put 3 wood blocks under the accumulator unit to get it level and then I could adjust the actuator arms, checking various times on different latch pins. Just follow the manual

[mexnielsen]

After adjustment I took off the magazine again. When I disassembled I took out the accumulator unit downwards without the top plate (PIB)



I found out that I could leave the top plate on and by loosening the screws on the record player unit and moving it sideways I could insert the accumulator unit from the upside



I connected all the plugs and it was time to "do" the record player.The rubber supports were gone all of them



I had ordered new ones from www.jukebox-world.de/en/Onlineshop/ together with 2 new belts



Looking good, but when I tried to fit them I found out that they were too "long" 15 mm instead of 1/2" as the old ones. My fault I didnt measure the old ones before ordering, I dont know if the Mexicans changed this because these 15 mm long ones should fit a Wurlitzer 1050

[mexnielsen]

I had to think a little about how to fix this. Looking from the front, the left side mounting bracket had space enough to move the screw holes the 4.6 mm needed, and adjustment for the center position could compensate the 2.3 mm off center.



I drilled and cut new M4 thread and the rubber supports fitted nicely
