Description
The ST458 was a mono quarter-track recorder with two speeds and a seven-inch reel capacity. Styling was quite bold for 1963, with a sloping fascia control and speaker panel at the front left of the machine while the front right hand panel housed all but two of the controls, the speed selector and the track selector being the exceptions.
Transport controls were of the push-button style and were, from left to right, record, pause, playback, fast rewind, stop and fast forward.
Stereo playback was possible using an external pre-amplifier (type EL3587) along with an extra amplifier and speaker. “Duo-play” and “Multi-play” were also possible with this amplifier.
Other features included parallel-playback, mixing of low and high-level inputs and the internal 3-watt amplifier and 6½-inch speaker could be used as a straight-through amplifier. The amplifier was of hybrid design, using two valves, five transistors, a selenium rectifier and one diode.
The Cossor Radio and Television company of 233 Tottenham Court Road, London also sold this recorder as the Cossor 1604.
