Description

The DSR1 has a rather confused pedigree.  Although it bore the HMV brand name, it was marketed by The Gramophone Company and built by The British Radio Corporation.  EMI owned HMV, and the British Radio Corporation was made up of HMV’s Radio & Television sales group, Marconiphone, Thorn and Ferguson, all of whom were marketing similar recorders under their individual names.
And if that wasn’t confusing enough, the DSR1 used a Verdik S1 deck.
Marketed as a budget-priced recorder (£50) with professional features, the DSR1 was a two-speed, half-track, 3 motor, 3 head recorder with separate record and playback amplifiers for off-tape monitoring, solenoid operated servo brakes and a pause control giving instantaneous stop-start .
Despite these features the recorder was not a huge success because performance was still only that of a domestic machine.
