Upper program selection switches & buttons

The three buttons (blue, yellow & red) and switches rotates the title drum.  The switches did not work due to dirt/dust on the ultra-small leafs, everything had to be aligned and cleaned with solvent.

A half switch, cleaned  and two not yet aligned leafs for one button.

Fixing the 60 Hz Motor speed and heat

As the jukebox comes from US the turntable motor runs on 60 Hz.

Here in Sweden we have 50 Hz, so to correct that I bought a spring from Stamann in Germany to mount on the motor drive shaft. Well it did fit perfect BUT the speed was around 40 rpm so it was just a waste of time and money.

Next problem was the motor was running heat caused of the 50 Hz, motor was around 70 degrees C HOT and the windings will probably melt down over time.

A large metal resistor (82 ohms 25W) is the solution here, voltage went down to 100VAC and the heat went down to 35-40 degrees C, I can live with that but a 50 Hz motor should be my final solution.

The motor in pieces, no radial play in the bearings (will cause rumble), and a 2,5mm axial play seems ok.

As it was impossible to achive the speed 45 rpm it ended up in the workshop at my work.

With the spring diameter in mind I estimated the outer diameter to be 5,35 mm.

The new turned ABS tube installed and slightly grinded in place now gives 45,1 rpm :-)

Note the resistors temperature!

This cooling fins will do it!

Title strip drum

 Here is the title strip drum, it's in a quite ok shape, cleaning and adjustment is of course needed.
All the songs seems to be from the era l968-70 so I assume the jukebox have been standing in a barn the last 45 years!

 Rusty parts

Of course did I miss the markings on the cogwheels when I disassembled all the parts but I assume all markings on the three cogwheels should be in the same line....

New own custom made decals for the title drum

Push buttons, switches and light diffuser

Rust and dirt on the forty switches, a cleaning was of course needed.

All buttons except no 33 was ok, had to buy a replacement from Bill Butterfield CA USA

Color diffuser mech rusty.....

Not much of the colors is left on the diffuser glass.

All push buutons was cleaned and I found that no 33 was really bad so i orderd a replacement from Bill Butterfield (Music For Fun)  in US.

Transparent plastic foil was the solution.

Not bad at all :-)

Popularity meter

The popularity meter is a mech part that counts how many times a record have been played, the design is bad and troublesome and many users removes this.

 But as I have all parts I decided to refurbish it.

The popularity meter concists of 60 small "cog wheels" washers, springs and lockrings that must be cleaned and polished. Almost all "cog wheels" are also deformed (due to the bad design) and must be aligned one by one.

Before the refurbish

The popularity meter is the orange long part in the center

All small parts after cleaning

Installed with a my own designed label, not prefect colors but good enough!

Grille stars

Four new stars from Stamann Musikboxen in Germany, 42 Euro ea.

Just pay and be happy that someone sells the stars......

Still I miss the center emblem, If you know where to find one drop me a line...

Selector cleaning

This was a PITA to do, as the springs loaded 30 pin's on the four sectors was almost impossible to get in place and fit intothe corresponding hole, I first tryed locking them with a small plastic gas hose but that didnt work att all. The spring loaded pins just launched like mini rockets just looking on them.

Finely after weeks of testing different solutions to hold the pins, I invented the "opposit spring solution" which hold the pins/springs in place.

The inner diam of the corresponting spring must be 4,5mm (spot on) to work.

Here is the selector after opening up, with 120 coils/springs/pins and 6 clapper coil asm in the center

Rubber hoses centers the springloded 30 pins.
