Additional Details


The TRE company (Tape Recorders (Electronics) Ltd) began life in 1953. Their first recorder was the ‘Editor’, one of the earliest and most commercially successful British-made portable domestic recorders.
When the Collaro company developed their reversible Mk IV ‘Transcriptor’
tape deck in 1957, TRE were among the first to use it, both the 777 (A19)
and A20 models were fitted with the Collaro Mk IV.
The Sound 777 was a half-track mono, three-speed 7″ reel capacity
recorder with reversible recording and playback.
The three-watt internal amplifier and 4 x 7 inch elliptical speaker provided
adequate playback, however the sound was considerably improved by using
an extension speaker (a jack was supplied for this purpose).
See the vintage test report below for a detailed description of the equipment.
