styling and outstanding quality performance’ were claimed by Telefunken
for this half-track stereo tape deck.
It was fitted with separate record and playback
heads which provided off-tape monitoring as well as echo and reverberation
Both channels were individually and separately
controlled, allowing two different programs to be run at the same time
in different rooms.
An unusual feature for Telefunken were the two Vernier
slide controls which were provided for record gain and also the inclusion of
two pre-set level controls for special effects.
Both front and back of the M250 cabinet were
finished in wood veneers, but Telefunken also offered (as extras) coloured
metal facings in red, white and green.
Price (in the UK) in 1968 was £157 10s.
