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)
