I actually bought this on ebay: https://www.ebay.co.uk/itm/Hohner-K2-International-Synthesizer/401409221743 Bargain!
I’m looking for any information about this machine: there are NO schematics or manuals to be had, anywhere on the web!
Hohner themselves don’t have anything (I asked them), as it was produced for them in Italy (probably ELEX)
Get in touch below if you have any info on this machine!
eBay description: “Very rare Synthesizer. Needs some service. Only bass section works and the fader knobs are missing. It might just need a clean and full service to get it going. Sell it as is. It’s been stored for many years in my storage. Please contact me for any question about the item. Thanks”
I negotiated with the seller: I paid £70 including delivery, and this thing is HEAVY! (> 20Kg)
