Description
This very unusual device was much like the English-designed Gramdeck, but pre-dated it by about 6 years.
Having no motor, the recorder was designed to sit on top of a gramophone turntable which then provided the rotational drive for the capstan.
A separate power unit supplied the necessary circuitry for bias and erase current, as well as record and playback preamplifiers.
A playback frequency of 40 – 7kHz wa claimed and a tape speed of 7½ ips was derived from a turntable speed of 78RPM.
Price when new (in Austria) was 1340 Schillings.
