Onbekend - Disco Light Cassette karaoke Portable cassette player

This is a vintage Disco Light Cassette Karaoke System, a collectible from the 1980s.
Features: The device has two cassette bays, built-in microphones, and a disco ball lighting effect on top.
Style: It has a distinctive pink and silver design.
The whole unit is in very neat and nice condition.
Everything works well, except the right cassette doesn’t. The motor runs well but the tape won’t spin; I think a new belt is needed here.
Usage: Designed for home use as a portable karaoke device.
