FM signals induced on a FM antenna are led to FM antenna coil L101 through a balun coil.
These signals are then applied to the FET RF amplifier which in turn applies its output to the
next Transistor Mixer H102 through the double tuned high selective circuits. The Mixer convert
its input signal into 10.7MHz intermediate frequency and amplifies it at the same time. The
H103 is a local oscillator and its output is injected into the base of Mixer transistor, the
injection voltage is about 50mV. The 10.7MHz front end IF output is led to the next IF
amplifier unit through a coaxial cable.
The IF amplifier unit consists of five stages of IF amplifiers. Two pieces of ceramic filters
are used to obtain high selectivity a pair of symmetrical diode limiter is also employed for the
best limiting characteristics, improved capture ratio and good AM suppression.
A part of IF amplifier H202 is rectified by the diodes H211 and H212 and its DC output is
fed back to the gate of FET RF amplifier to decrease the gain of it with increased input signal
strength.
3-1. Muting and Auto-Stereo Switching Circuits
The muting circuit consisting of all solid-state electrical switching has been incorporated in
the Model 2220B.
The DC voltage obtained by rectifing the sub |F output signal from the H206 is applied to
the base of H207 and turns on it, if the sub IF output is greater than predetermined level
(muting threshold level).
When the H207 turns on, the muting switch transistor H208 is turned on, thus decreasing
the emitter collector resistance to near zero ohm and allowing emitter current path to the Final
1F amplifier H205.
When the input signal is lower than the predetermined level, the DC output obtained is small
and can not turn on the H207 thus the H207 keeps its turn off state and this makes the switch
transistor keep H208 turn off, then no emitter current is supplied to the H205 and signals below
the threshold level are muted out.
The muting threshold level can be varied by adjusting the trimming resistor R253.
The DC voltage obtained is also used to.make the Auto-Stereo switching transistor H209
turn on and off.
3-2. MPX Stereo Decoding Circuit
The stereo composite signal from the FM detector undergoes a phase compensation by
R303 and C304, is applied to the input terminal pin 2 of the MPX stereo decoding IC H301 on
a PLL (Phase Locked Loop) basis, and decoded into the left and right stereo signals, which
become available at pins 4 and 5 respectively. These decoded left and right stereo audio signals
are introduced through a !ow pass filter composed of L301 to L304 and C309 to C318 for
elimination of undesirable residual switching signal and through a de-emphasis network
consisting of R314, R315, C319 and C320, into the npn-pnp direct coupled audio amplifier,
where the signals are amplified to a required level for the output from J307 and J308. From
these terminal the audio signals are led to the TAPE OUTPUT jacks through the function
switch. Figure 1 presents an internal block diagram showing the functions of the PLL basis MPX
stereo decoding IC HA1156. The input stereo composite signal, amplified by the audio
amplifier, is delivered to the phase detectors PD-1 and PD-2. A part of the stereo composite
signal is also applied to the stereo decoder section. The VCO (Voltage Control Oscillator)
produces a free run oscillation in the neighborhood of 76KHz with the time constant
determined by a capacitor C303 and resistors R304 and R305 set on the outside of pin 14.
The VCO output has its freqeuncy divided into 19KHz through the two stages of the frequency
divider (DIV-1 & DIV-2), and is reverted to the phase detector PD-1, which contains two input
terminals designed to produce an output in proportion to the product of the two input signals.
The signal applied to.one of the inputs of PD-1 is the 19KHz square wave formed through
frequency division of the 76KHz VCO output signal by the two stages of the frequency divider

2. AM TUNER
All components except ferrite bar antenna are mounted on a printed circuit board P100.
The
AM
signals
induced
in
a
ferrite
bar
antenna
are
applied
to
the
RF
amplifier
section
of
’ the AM tuner IC H104 through a capacitor of C129 and amplified to the level required for
overcoming the conversion noises, thus giving good S/N performance. The tuned circuits
inserted in both out and input circuit of the RF amplifier assure very high image and spurious
rejection
performance.
Thus
amplified
and
selected
AM
signals
are
then
applied
to
the
converter
section
through
a
coupling
capacitor
C132.
While
the
local
oscillator
voltage
is
injected
through
a
capacitor
C131,
both
AM
signals
and
oscillating
voltage
are
mixed
and
converted
into
455K
Hz
intermediate
frequency.
The
resulting
IF
signal
is
applied
to
the
first
IF
transformer
L110
consisting
of
one
ceramic
filter
and
two
tuned
circuits.
The
output
of
L110
is
led
to
the
IF
amplifier/detector
section
of
H104.
The
detected
audio
signal
is
obtained
from
PIN
11
of
H104
and
amplified
to
a
required
level
(about
470
mV
far
400Hz
30% mod.)
by
the amplifier
H105 and
fed
to
the
function
switch.
2.1
Suggestions
for
AM
Tuner
Trouble

Check
for
broken
AM
bar
antenna,
next
connect
an
oscilloscope
to
the
pin
11
of
H184
0
J112 and
check
for
audio
signals
with
the tuning
meter
deflected.
If detected
audio signal
is
obtained
at pin
11
of
H104,
no
failure
may
exist
in the
AM tuner
IC
H104
and
its
associate¢
circuit.
If
no
audio
signal is
obtained
at
pin
11
of
H104,
check
all
voltage
distribution
in
ths
AM
circuits by
using a DC
VTVM.
3. FM TUNER
The
FM
Tuner
section
of
Model
2220B
is
divided
into
three
functional
blocks:
FM
fron
end, IF amplifier & Detector, Muting control and MPX stereo decoding circuit.

DIV-1
and
DIV-2,
and
the
19KHz
pilot
signal
included
in
the
stereo
composite
signal
as
a
reference
signal
is
applied
to
the
other
input.
Therefore,
the
output
of
PD-1
which
has
passed
through
the
low
pass
filter
LPF-1
provides
DC
output
voltage
in
proportion
to
the
phase
variance
between
the
two
inputs.
This
DC
output
voltage
is
amplified
by
the
DC
amplifier,
and
supplied
to
the
76KHz
VCO
as
a
contro!
voltage.
This
means
that
the
output
frequency
and
phase
of
the
VCO
have
been
phase-locked
to
the
input
pilot
signal.
The
38KHz
sub-carrier
reproduced
by
PLL
as
stated
above
is
delivered
through
the
stereo
switch
to
the
stereo
decoder
section
as
a
switching
signal,
thus
driving
the
decoder
section.
One
of
the
inputs
of
PD-2
is
given
the
19KHz
resulting
from
the
frequency
division
completed
by
DIV-1
and
DIV-3,
whereas
the
other
input
gets
the
19KHz
output
contained
in
the
composite
signal,
and
the
output
is
provided
with
a
DC
output
in
proportion
to
the
amplitude
of
the
pilot
signal.
This
DC
output
is
furnished
through
LPF-2
to
the
trigger
amplifier
which
drives
the
stereo
indicator
lamp
and
stereo
switch.
Therefore,
insufficient
supply
of
the
pilot
signal
results
in
failure
to
light
the
stereo
indicator
and
to
turn
on
the
stereo
switch
located
in
the
path
of
the
38KHz
switching
signal,
thereby
avoiding
a
wrong
stereo
operation.
H303
attached
on
the
outside
of
pin
8
isa
switching
transistor
for
automatic
monaural-stereo
switchover.
When
the
intensity
of
an
incoming
signal
from
an
FM
station
is
weaker
than
a
predetermined
level,
this
H303
is
turned
on
and
pin
8
is
grounded,
thereby
developing
a
condition
for
monaural
reception.
For
a
forced
monaural
operation,
switch
the
MODE
switch
to
“NONO,”
an
H303
comes
into
an
“On”
condition
with
the
positive
bias
voltage
applied
to
the
base,
and
pin
8
is
grounded,
thereby
establishing
monaural
operation.
The
transistor
H302
connected
externally
to
pin
14
is
intended
to
stop
the
76KHz
oscillation
of
the
VCO
Which
interferes
an
AM
signal
during
the
reception
of
an
AM
station.
When
the
function
switch
is
set
to
‘“AM”
position,
a
positive
bias
is
charged
on
the
base
of
H302,
H302
is
turned
on,
and
pin
14
is
grounded.
Thus,
the
oscillation
of
the
VCO
is
stopped,
ending
the
interference
with
AM
reception.
3.3

knob
slowly
and
observe
the
FM
tuning
meter.
lf
the
turning
meter
deflect
at
several
frequencies
received,
the
tuner
circuits
preceding
the
discriminator
circuit
may
have
no
failure.
When
no
reading
is
obtained
in
the
meter,
check
FM
local
oscillator
circuit,
using
a
RF
VTVM.
The
normal
local
oscillator
voltage
is
one
or
two
volts
(fms)
at
the
tuning
capacitor,
depending
on
the
tuning.capacitor
position.
If
the
local

voltage
is
normal,
next
check
all
voltage
distributions
in
the
FM
Front
End
and
IF
amplifier
unit
and
compare
them
with
those
shown
in
the
circuit
diagram.
When
the
tuning
meter
deflects
but
no
sound
is
obtained,
check
audio
circuits,
using
a

Signals
from
the
PHONO
jacks
are
applied
to
the
phono-amplifier
consisting
of
transistor
H401,
H403
and
H405.
The
gain
of
the

HEO7. Frequency response of the amplifier can be varied by BASS, MID and TREBLE controls.
The controlled output are then led to the main amplifier through high and low pass filter
pushswitches.
5. MAIN AMPLIFIER
Transistor H701 and H703 are a differential amplifier coupled to the transistor H70O7.
Transistor H707 drives the inverter transistors H721 and H723 which, in turn, drive the power
stage consisting of HOO1 and HOO2. Transistors H709 and H721 are current limitters and
operate as power protecting circuits.
Excessive currents flowing into the power stage are detected by the resistors R749 and
R747 and the resultant variations are applied to the transistors H709 and H711 and make them
turned on. This decreases the current flowing into the H721 and H723. In this way the currents
flowing in the power stage (HOO1 and HOO2) are restricted within a safe value.

2. Set the signal generator to 1650 KHz. Place the tuning pointer in the high frequency end
and adjust the oscillator trimmer on the oscillator tuning capacitor for maximum audio
output.
3. Repeat step 1 and 2 until no further adjustment is necessary.
4, Set the generator to 600 KHz, tune the receiver to the same frequency and adjust a slug core
of AM ferrite rod antenna and RF coil L108 for maximum output.
5. Set the generator to 1400 KHz and tune the receiver to the same frequency and adjust both
trimming capacitor of antenna and RF tuned circuit for maximum output.
