GENERAL
INFO
RMAT ION
Roberts Models
90, 90-S,
and
90-C tape recorders consist of
two
basic sections
--
a
tape-transport mechanism
and
a record-playback amplifier.
The Model 90
is
a
monaural tape
recorder.
Models
90-S and
90-C are stereo
tape
re-
corders.
Stereo can be recorded by connecting a Roberts
Model A-901
stereo
amplifier
to
jack
2
on
the stereo tape
recorders.
On
the Model 90-C,
a preamplifier
is
included
for
the
lower
channel.
The mechanical
controls are interlocked to prevent accidental selection
of
an
incorrect
operating
mode.
r
The Roberts
tape recorders
have
two speeds,
7 L/ 2
and 3 3/ 4
ips.
With both
monaural
tracks,
