Hi I got a Hope Studio 7550 from the 70's. It doesen't work properly and I can't find any info/schematics about it at all. Just two
other threads from this site:

Anyone here have some more info about it and perhaps some schematics?

Best regards.

You are right, it's impossible to find anything more than the above. Maybe the best way would be to find the original creator - or at least owner of the factory - Thure Barnsøe-Carnfeldt. Facebook / Linkedin / or personally?  He now lives in Dronninglund (see Barsøe Carnfeldt on KRAK). And why not? It's a part of Danish hi-fi history, which we obviously don't know much about, so it's about time for somebody to discover, what may be able to discover, and write the story or just some technical knowledge, so there will be something to find the next time, somebody finds the Hope. If he is able to, I feel sure, Barnsøe-Carnfeldt will help you. Maybe even be glad to - and for someone remembering his work. So please give it a try.

I've contacted Thure thru Facebook, i Hope that he want to help My cause.
