First cassette deck from Revox , which had already produced excellent tape machines
The frequency response of this deck reached, for example, that of the Tape machine Revox A 77 at half tape speed
Drive assembly without straps and slip clutches

Stereoplay 9/1982: "Top class II" (same group as the legendary Nakamichi Dragon; best classification of cassette decks at Stereoplay in time; at tape machines "Top class I").
