TR.MK.5 (Mk 5)

Mono tape recorder with a gold hammered enamel deck plate with an ivory head cover and a mushroom-beige Rexine covered plywood cabinet released in April 1958. Digital tape counter. 1/2" and 1" capstan sleeves, up to 8.25 inch reels, 3 motors, belt-less, four speeds (1.875, 3.75, 7.5 & 15 ips) with frequency correction at all speeds. The standard Brenell had an erase head and a combined Brenell record/playback head but had provision for two more heads to be fitted. In the summer of 1958, staggered stereo was an available option and employed a pair of staggered stereo erase and record/playback heads which allowed reproduction of the commercially made American staggered stereo tapes.

Three more variants of the Mk 5 followed, the Mark 5 Series 2 model and the Mark 5 type M (Mk.5M) model in 1962, and the Series 3 model in 1963.
