“As easy as putting on a record! – Slip the Gramdeck on to your turntable and you have the finest tape recorder you’ve ever heard. Lift it off and your gramophone is ready to play records again”.
Sounds too good to be true??
The unit (which could accommodate spools of up to 5¾” in diameter) slipped onto the turntable which was then used to drive the tape spools – the audio section of the existing gramophone / radiogram / hi-fi system was utilised via connecting leads through the control unit.
The control unit was fully transistorised and powered by an internal battery. It featured a microphone input and controls for play, record etc.
Fast forward/rewind didn’t appear among the advertised features. (It’s hard to imagine one’s leisurely turntable being able to deliver anywhere near enough torque to accomplish this!)
The advertised Gramdeck features DO include however:
Twin track head, automatic erase, sound on sound, direct recording from radio, fits any spindle, easy to fit, very reliable.
What a concept!!
