The Sound ‘Slimline’ series was launched in the autumn of 1961. The first models, A37 ‘One-Two’ (single-speed, half-track) and A38 ‘One-Four’ (single-speed, quarter-track) used the 3¾ ips 5¾” spool BSR TD2 deck with half or quarter-track heads.
In late 1962, the slightly more upmarket A39 Slimline ‘Three-Two’ and A40 Slimline ‘Three-Four’ were launched, both utilising the three-speed Collaro Studio deck. As the name suggested, these recorders had three speeds and came in two or four-track configurations. In 1963, the Slimline series took on Sound’s new TRE prefix (Tape Recorder Electronics) and became known as the TRE 32.
The machine pictured at left is a Slimline ‘Three-Two’, a two-track, three speed recorder with push-button operation and facilities for superimposing, monitoring, mixing and using as a straight-through (3.5 watts) amplifier.
Price when new was £42 complete with microphone, tape and spare spool. The four-track version (A40 ‘Three-Four’) was priced at £47 5s.
