CIRCUIT
DESCRIPTIONS
F ig. 1 Tuner
Section
TUNER
SECTION
FM Front
End
A frequency linear 3-gang variable capacitor is
used with a single stage FET RF amplifier. The
FET possesses
high input impedance compared
with a transistor, and allows simple coupling with
the input tuning circuit, plus a significant advan-
tage
in terms of noise.
The local oscillator is a variation of a Clapp circuit
and its excellent temperature compensation
provides stable frequency even without AFC.
Local oscillator voltage is passed
through a low
value capacitor to the mixer transistor base.
lF Amplifier and
Detector
Composed
of two dual element ceramic
filters and
one IC (HA1137). The HAl1BT is a high density
IC and contains a limiter amplifier, FM detector
(quadrature detector), muting, and meter drive *21
circuits.
Multiplex Demodulator
The IC (HA1156W) used
in this section
does
not -1s
require a tuning coil and in addition to a pLL
stabilized switching signal generator circuit, it
contains a double balanced differential amplifier
switching system demodulator circuit and an auto_
matic stereo-mono selector circuit. An extemal
switching transistor controlled by the FM muting
signal provides automatic monophonic reproduc-
!t_91
"t input sigrrals
below the muting level (FM
MUTING switch OFF). The stereo demodulator
signal passes
through the de-emphasis
circuit, then
through an amplifier that combines carrier filter
and crosstalk canceller to produce the demodula_
tor output.
AM Tuner
Composed of a single IC (HA11BS) and dual
element ceramic filter. A 2-gar,:rg
variable capacitor
is employed with one stage
providing tuning be_
tween the antenna and RF amplifier and the
other stage tuning the local oscillator. The RF
amplifier itself is not tuned but feeds direcfly to
the mixer followed by a 2-stage IF amplifier.
PHONO
EOUALIZER
AMPLI FIER
IC (TA7136P1) is used with independent left and
right channels.
Tolerances
!2Vo styrole capacitors
and tolerances !1Vo metal oxide resistors comprise
the equalizer elements,
leading to an RIAA devia-
tion within 0.3dB from 30Hz to 15kHz.

Equalizer
MICROPHONE
CIRCUIT
A single transistor amplifier (monophonic) is
provided in addition to the phono equalizer
ampli_
fier. A selector switch cuts the AUX jack iniut
when a plug is inserted into the MIC jack. ihe
amplified microphone signal is then supplied to
both the left and right channels.
The FUNCTION
switch is set to the AUX position when using a
microphone.
When the power switch is set to OFF, point C
potential instantly becomes
- 16V. Q4 becomes
ON and C2 is immediately discharged. Since this
interval is extremely brief, the muting time remains
constant even if the power switch is again set to
oN.
Fig.
3 Microphone Circuit
TONE CONTROL
A CR network tone control circuit is employed in
which each attenuator circuit consists of a capaci-
tor and a resistor. These function to increase and
decrease the relative levels of low and high fre-
quency sounds. Since relative control over the fre-
quency response by the attenuator results in a
constant loss, an amplifier (Q1 & Q2)
is used
prior
to this stage for compensation. The control ranges
are +8dB to -8dB for the highs (at 10kHz) and
+9dB
to -gdB for the lows
(at 100H2).

MUTING
AMPLIFIER
When the power switch is set to ON, the potential
of point C in Fig. 5 instantly rises due to C3 &
Rb time constant, and Q4 becomes
OFF. Point B
potential at this time gradually increases with the
C2 & Rg time constant and normally reaches
-19V.
Q3 becomes OFF when point B is below -15.4V,
from which time point A potential rises with the
CL & Rl time constant and normally reaches
approximately 8V from R1 & R2. FET Q1 & Q2
operate when point A potential is above 0V. The
muting interval (T) extends from the time the
power supply is set to ON to when point A poten-
tial reaches 0V. This interval is set f.or 6 - 7
seconds.

AMPLI FIER
CIRCUIT
Composed of differential first stage, all stages
direct coupled pure.complementary OCL circuit.
Open gain at lkHz is approximately 80dB and
NFB amount is approximately 50d8. R3 and R4
are provided with this circuit in order to obtain
adequate stability even
with the NFB disconnected.
Q1 form a differential amplifier: IIOVo d.c. feed-
back is applied from the junction point of the
power stage to the base of Ql so the potential of

POWER
SUPPLY
High stability (ripple cancelling efficiency) is
required in the power supply circuit due to its
minimized output impedance.
In the circuit shown
in the Fig. 8, Q1 is controlled by Q2, which detects
its output variations. Tuner power is taken from
Q3 emitter. Since
this is at the power transformer
secondar5r,
AC line variations
do not directly reach
the tuner.

9. Adjust TC3, then TC1 and TC2 for maximum
indication on AC VM.
10. Again set FM SG and SX-550 dial indication to
point A.
11. Adjust T3, then T1 and T2 for maxirnum indi-
cation on AC VM.
12. Repeat steps 8-11 to eliminate variations in
sensitivity at points A and C.
13. Adjust T4 for maximum sensitivity.
14. Detune to noise only and adjust Tb lower core
for center of scale indication on Tuning meter.
15. Set SX-550 dial indication
to point B (98MHz)
and adjust FM SG for center of scale indication
on Tuning meter.
16. Set FM SG output to 60dB and adjust Tb
upper core for minimum distortion.
