Danish collector Flemming Sorensen sent the following pictures and text from a book entitled “Sound from past to present” which he found in his local library.
This is the one that started it all. It is the first production tape recorder. Not only is it of historical interest but it is also technically quite different from later models. The tape speed was very fast – (1 meter per second) yet the sound quality was little better than the quality possible on 1 7/8 ips 25 years later.
