AMI Continental / AMI Conti 1 und 2 - Jukebox-World
This auto-mix-kit worked in both directions - from 33 to 45 rpm and the other way around. The records with a small centre hole were "known" and the turntable speed was slowed down; this was also optional with Rock-Olas 1961 models. Most of Conti 2 models these days are missing this auto-mix kit.
