the
By
the
use
of
FET
(field effect transistor)
in the FM
radio frequency amplifier
stage, design
of
nearly perfect
FlVl
front-end
was achieved-free
from
cross
modulation, free from
drift, with
better sensitivity, lower inherent
noise,
and
high
spurious
rejection ratio.
ln the
FM intermediate frequency amplifier stage, integrated circuits
are employed,
resulting in an entirely different outstanding performance
from
that of
lFstages
hitherto
designed, especially
in the
limiter
characteristic and the capture
ratio.
The
accurate electronic switching circuitry
is
employed
in the
FM
multiplex
demodulator, insuring maximum
separation
with
excellent
tonal
quality.
The muting circuit
provided
in the
FlVl
tuner
completely eliminates
the
FM
inter
station noise
whrch has hitherto
been
annoying
the
user in
tuning.
The
power
amplif
ier
employs
the
high-performance single ended push- pull
circuitry
in
the output
stage and
the push,pull
complementary
circuitry in
the
driver stage, completely eliminating
the
distortion rnherent transformers
from
the
audio stage. Tripple diffused
mesa transistors are adopted
as the
power
transistors
in
the output
stage
for
full-fidelity
frequency response
with
large
audio output power and
least harmonic
distortion.
The inputs and outputs pr,ovided
in
the
receiver
include two pairs
of pHONO
MAG
inputs. When
two
turntables are
connected
to
these
inputs,
the
user
is
able
to
switch
from
one
turntable
to the
other any time at
will. Also, two
pairs
of
ioudspeaker outputs are included
for
switching
between,
or for
per-
mitting the simultaneous use
of, two
loudspeakers.
The electronic switchrng circuitry
employed in the power supply completely protects
expensive
power
transistors
even
when the
loudspeaker leads are shorted
while
the
receiver un,L
is
in
use
INSTALLATION
As
this
receiver
is sully transistorized, desirable places
to
install
it
are
as
follows:
OPlaces airy and
free
from
humidity and dust.
Avoid insta
ling
on
close,
low-ceiling
shelves.
OPlaces not
directly
exposed
to the
sun
ray.
OPlaces not close
to
heat-emitting
objects
such as heaters
and
stoves.
LINE
VOLTAGE SELECTION AND
FUSE
Switching Line
Voltage Setting and
Fuse
In
order
to
remove
the fuse,
turn
the fuse
cap
located
on
the
line voltage
selector switch in the
direction indicated by an
arrow.
Then
remove
the
fuse plug
from the unit.
Put
the
fuse
plug
back so
that the proper
line
voltage
marktng can
be seen thru
the
cut
on the
edge
of the
plug.
Whenever
the set position
of
the
selector swttch
is
changed,
check
the
rating
of the
fuse.
A
1.5-ampere
fuse
is
to
be
used
for either
220\l
or 24OV
operation
and
a
3-ampere
fuse
for
any
of
110V,
117V,
or
130V
operation.
lf
the
rating
of
the
fuse is proper,
install the fuse
on
ihe fuse
cap.
OPlaces where there is as little vibration as possible
and where
the
surface
is
level.
The
optimum
stereophonic
listening position
is
across
the
room
from the
speakers, sornewhere close
to
the midpoini
between
the right and leit
speaker
systems.

OReplacing
of
Fuse
When
the fuse
is
blown
off,
remove
the fuse
cap and
replace
the fuse with a
new
one.
