Description

A remarkable machine for its price with room for up to five heads, making it an extremely versatile
recorder at a time when dual-track, single track, mono and the new “binaural” (stereo) options were all still being used. The head-rack allowed for instantaneous switching of the head configuration.
Available in either 3¾ and 7½ ips or 7½ and 15 ips, the 20/20 was equipped with three heavy duty motors. the tape drive was supplied via a two-speed capacitor-induction motor and two shaded pole motors for take-up and rewind (the latter functioning at 2,400 ft/minute with a lever giving variable control). The tape transport contained no belts and produced less than 0.1% wow and flutter at 7½ ips, even less at 15 ips and reels of up to 10½ inches were catered for.
The tape transport control was a single lever and the machine had an automatic cut-off at the end of the reel or in event of a tape break. Constant and unvarying tape tension was supplied by means of tension arms at each end of the tape path, threading was straight-line and very simple and rapid.
