The 1953 Pyrox Magictape ST1 was manufactured
in Australia under license from the Armour Research Foundation of USA.
This was one of the first commercially available recorders in Australia
and was also sold under the AWA brand name.
It was a single speed 7½ ips half-track mono recorder with a 5
watt output and an internal 9″ x 6″ elliptical speaker.
A simple, single control was provided for forward, rewind and fast forward.
Time scales were printed on the base plate beneath both reels to indicate
The Magictape continued in production
until the late 1950s, undergoing only minor cosmetic changes. The first
models had no fast forward, only rewind. Fast forward was effected by turning
the reels over and using rewind, then reversing the spools again to play.
The tone control was operative on playback only. Price when new (in 1953)
was AU £135. 8s 4d.
