Converting to free play, coverting to payed or chang the amount of plays

To convert the jukebox to free play (or other way around) is very simple just remove (or place)  the Credit unit reset pawl in the accumulator unit.

Below, the location of the accumulator unit (leftside in the middle)

the reset pawl

Changing the amount of plays

Default the jukebox will play one song for 5c, two plays for 10c and five plays for 25c, you can change this:

Original the jukebox has 110V and 60Hz, in Europe with the step down transformer, it gets 110V and 50Hz

This means that the Turntable motor is running slower on 50Hz than on 60Hz.
To solve this you screw the conversion spring on top of the shaft of the turntable motor,  above the original 60 Hz. spring.

This increases the diameter to 5 – 5.1 mm. (use a Caliper to check the spring)

Do not remove the original 60 Hz. spring!

Sadly when I played a song on the jukebox is was howling (changing speed)

The original idler wheel was slipping on the turntable, I bought a new one.
After changing the wheel I noticed that is playing to fast, so bough a other one on a other website.

My collection Idler Speed wheels, the black-one is the original one and afer testing the bronze one (from  http://www.jukebox-world.de) gave exact 45 Rpm

To test the speed I used the RPM Turntable speed app from Philip Broder on my phone. (example for 33Rpm below)

My Jukebox is imported from the USA and is designed for operation on 110V only. Next to a conversion to the European frequency of 50 Hz. it is needed to convert the voltage from 230V to 110V. Therefore a step down transformer is needed.

Since I read an article in a magazine about problems with the fact that in Europe the Voltage is boosted from 220V to 240V the step down transformers are giving also a higher voltage than 110V , I took my voltage meter and measured what my Transformer did and noticed that my voltage was 122V, this is not good (it should never be above 115V).

If the voltage is higher that 115V you can get fire or serious electric shocks, so be aware and do not trust you old step down transformer.

I also had a humming noise when I touched the metal of the jukebox, to solve both problems and give my jukebox a longer lifetime, I bought a Isolating Transformer at www.Jukebox-world.de

The new Isolating transformer, solved the humming noise and lowerd the heat of the TL Trafo and the turning table motor.

One of the best investments ever.

Isolating transformer,

My next challenge is going to be the 50Hz to 60 Hz conversing.
