Additional Details


A quarter-track stereo, all-transistorised recorder aimed at the hi-fi enthusiast,
the Dynatron STR1 utilised a three-speed, single PAPST motor deck made by Garrard (in collaboration with Dynatron). The deck featured three heads, a large central keyboard for transport control and a solenoid controlled auto-stop. The ST1’s production life was cut short due primarily to Dynatron becoming absorbed into the Philips group, who, it may be recalled, had a few tape recorders of their own to market!
Price when new: £82. 19s.
