This was mistakenly advertised as a Karaoke machine. It isn’t a Karaoke machine. Nevertheless I took a punt on buying it as I had the feeling that I owned the unusual cartridges it plays. In this video you can see if my hunch paid off and learn more about a rare format through an even rarer player. My earlier video about this format https://youtu.be/Q_9IBIcsYj4 UPDATES: I) The machine appears to date from approx 1976. A helpful person on Patron spotted a date code on the speaker. II) Crown? Weren’t they a US/U.K. brand? (delete as applicable) - not this Crown https://commons.wikimedia.org/wiki/Category:Crown_(audio_brand)
