2. AM Tuner
Al components except Tuning capacitor and 1 errite bar antenna are mounted on a prin nted
| circuit board P150.
“The AM signals induced i in a ferrite bar antenna are > applied to the base of RE amplifie
transistor H151 through a capacitor of C151 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 ВЕ amplifier assure very high image and spurious rejection performance.
Thus amplified and selected AM signals are then applied to the base of converter transistor H152
through a coupling capacitor C156. While the local oscillator voltage is injected to the emi tter of
H152 through a capacitor C157. Both AN signals and oscillating voltage are mixed at the
base- emitter junction and converted into 455KHz intermediate frequency. The resulting IF signal
is applied to to the first IF transformer 1153 consisting of one ceramic filter and two tuned circuits. |
The output of L153 is led to the transistor H153 which in turn apply its output to the
transistor of next stage H 154. The fully amplified IF output 15 then applied to the diode H157 to
detect audible signal through the detector transformer L154. The detected audio signal is filtered —
and amplified and the final audio output is obtained from the collec tor of H155 and applied: one
to the tape out jacks through monitor switch on the front pa nel and the other to the function a
rotary switch. IE MENT | | | TE
The DC component of the detected Ta signal 15 used as a AGC ‘voltage to control emitter
current of H153 which: in turn control the bias current of the. RF amplifier through the resistor Ea
R179 and RA 51, A Part of UF signal output is also applied to the diode H158 through a capacitor |
C167 and rec tifie 2d to ob ain De current for energizing the AM signal streng th meter MOCT.
Suggestions for AM Tuner Trouble Shooting
Check for broken AM bar antenna, next try to tune station by rotating fly-wheel tuning knob
slowly and observe the AM signal strength meter whether it deflects or not. If the signal strength
meter gives a deflection at several frequencies received, no failure may exist in the stages at least
preceding final IF transformer L154. Next connect a oscilloscope to the pin terminal J162 or
1157 and check for audio signals with the tuning meter deflected. If the signal strength meter
does not deflect, check the local oscillator circuit. Normal oscillating voltage at the hot end of
the oscillator tuning capacitor is shout 2 or 3 volts, varying with tuning capacitor position. When
measuring oscillating voltage use a RE VTVM, no circuit tester gives correct indication, If the
local oscillator voltage is normal, check all voltage distribution in the AM circuits by using a DC
VTVM and compare the measured values with those given in the schematic diagram.
3. FM Tuner
The FM Tuner section of Model 2245 is divided into five functional blocks: FM Front End, IF
Amplifier, Detector, Muting Contro! and MPX Stereo Decoding Circuit.
FM signals induced by a FM antenna are led to FM antenna coil L101 through an attenuator
switch and a Balun coil. These signals are then applied to the FET RF amplifier which in turn
applies its output to the next FET Mixer H102 through the double tuned high selective circuits.
The FET Mixer convert its input signal into 10.7MHz intermediate frequency and amplifies it at
the same time. The H103 1sa local oscillator and its output is injected into the source of the FET
— Mixer, the injection voltage is about 700mV. The 10, Mhz front end output is led to the next IF
Ш amplifier unit through a coaxial cable.
| The IF amplifier unit consists of five stages of | amplifier and one stage of AGC amplifier. Six
— pieces of ceramic. filters are also used to obtain high selectivity four stages of symmetrical diode
limiters are also employed for the best limitting characteristics, improved capture ratio and good
AM suppression.
A part of FM Front ‘End output 15 15 applied to the AGC amplifier 1206 and rectified its output
is fed back to the gate of FET RF amplifier to decrease the gain with increased signal strength.
~~. The IF signal sufficiently amplified through every stage of IF amplifier is finally applied to the
Ш Ic limiter on the Detector Unit, The detected audio output is led to the buffer amplifier H502
; and its buffered output 15 led to; (a) noise amplifier H551 through resi stor R551 and capacitor
- C551, (b) Quad Radial Jacks on the | rear panel through resistor R564, { c) MPX stereo decoding
Е circuit through R563. о | | |
The DC current caused at the third windings of the discriminator transformer is directly
applied to the FM center tuning meter.
Audio Muting and Stereo mode auto- selecting circuit
The muting circuit consisting of all solid-state electrical switching has been incorporated in the
Model 2245. Three inputs control the muting function. The first is related to signal strength, the
second to the noise condition at the detector and the third is derived from the DC component of
the detector output. These inputs are properly matrixed and gated to provide muting free from
noise and transients.
The first input of DC voltage obtained by rectifing a part of IF output signal from the H205 1s
applied to the base of H306 and turns on it, if the !F output is greater than predetermined level
(muting threshold level). When the H306 is turned on the H307 is turned off, allowing the
emitter-collector resistance increasing ‘and the collector voltage rises about 8V. The increased
collector. voltage increases the gate bias voltage and turns on the switching FET H308, decreasing
the source- drain resistance to near Zero ohm and allowi ing the audio signal applied to the source
to flow to the center of 38KHz switching transformer through the source-drain path.
When the input signal is lower than predetermined level, the DC output obtained is small and
can not turn on the H306, thus the H306 keeps its turn-off state and this makes H307 turn on,
decreasing the collector voltage and turning off H308. Thus no audio signals can pass through the
FET. This is the fundamental principle of the muting operation but for more elaborate muting
operation the second and the third inputs are necessary,
The second input is used to protect the muting operation and MPX stereo beacon lamps from
misoperation due to undesirable noises. 1he high frequency noises included in the detected
audio signals. are separated. by a small. capacitor C551 and amplified by the noise amplifi ter
transistor H551 and its output 15 rectified by the two diodes. The rectified DC output is |
proportional to the noise components. in the audio signals.
When there are excessive noises in the audio. signals such as obtained with a à station incorre сиу
tuned in,the rectified DC output turns on the transistor H522 , decreasing the emitter- collector
— resistance to zero. This means the collector of H307 is short- circuited to the ground, therefore
. the H308 is turned off and any audio > signals havi ing excessive high frequency noises can not go
| through the FET's sourcedrain path. | a |
“The transistor H303 connected in series with у ‘the 19KH2 pilot signal amplifier transistor H302
ds also turned off (when the transistor H522 or H307 are turned on.) and no current flows i in the
H302, resulting. in turning off the stereo beacon Tamps. Thus misoperation due to undesirable
- noises is also avoided. | |
The third i input is obtained from the FM discriminator circuit. The DC output so y called ug"
-—— curve-is applied to the gate of H558 through a resistor R523 and deviding network (R56 o &
© R566). The DC output is Zero with a station correctly tuned in, but will vary from negative to
positive values or vice versa when the tuning point 15 deviated toward either plus or minus
frequency from the correct tuning frequency. |
When the DC output IS increased toa greater evel than that of predetermined, the increase ed
source. potential of H558 makes the transistor H561 turn on, and this makes the. H306 turn off,
H307 turn on, … . H308 turn off, … H303 turn off (this means no 19KHz pilot signal is
amplified and no stereo beacon 15 turned on.) When the DC output is increased to the négative
predetermined level, the decreased source potential turns off the H559 which in turn makes the
4560 turn on and the H306 is t turned off. The subsequent changes are exactly the same as that
just described above. SU
Thus when the tuning is shifted or deviated to the certain frequencies in which undesirable
noisy side- audio signals are produced, both muting and 19KHZ switching transistors are e operates |
automatically and open the circuits. Co -
With the station correctly tuned in, the. pias current of the FET 14558 18 adjusted 50 that both
transistor H560 and H561 are not turned ¢ on, giving 1 no effect ¢ on 1 the transistor H306.
ВЕ мех Stereo Decoding Circuit
“The buffered and non-equalized audio signals are applied to the first amplifier H301 which
| serves as a tuned amplifier for the pilot signal in the composite signals and as a buffer amplifier for
‘the audio signals. The amplified 19KHz pilot signal is led to the second 19KHz amplifier H302
and further amplified if switching transistor H303 in turned on by the controlling DC signal as
lescribed in the preceding chapter. The final 19KHz pilot signal is rectified by the doubler circuit
consisting of the H315 and H316 to obtain synchronized 38KHz amplifier driving signal.
~The H304 is the 38KHz tuned amplifier and supplies its output to the switching matrix circuit
: consisting of four diodes. While the composite signals are applied to the center tap of switching
В transformer 1/2 L302. The right and left stereo signals decoded by the switching circuit are led to
; the crosstalk cancelling amplifier which utilizes complementary configuration with NPN and PNP
transistors through de-emphasis network consisting of C315 and R335, and C316 and R336.
4305 15 a low. pass filter networks having very sharp cut off characteristics and eliminates
‘undesirable residual switching signals. Transistors H313 and H314 are buffer amplifiers and their
| outputs are led to the function switch.
Suggestion £ for Trouble Shooting of FM Tuner
Symptom: No FM Reception |
First turn on the power switch and try to tune FM stations. Rotate the fly-wheel tuning knob
slowly and observe the FM signal strength meter and FM center tuning meter. If the center tuning
- meter deflect at several frequencies | received, the tuner circuits preceding the discriminator circuit
may have no failure. 1f the signal strength meter deflect but no deflection is obtained on the
center meter, there may be some defects around the detecting circuit consisting H501, L501,
H503, H504, etc. When no reading 15 obtained in both meters, check FM local osci ¡Mator circuit,
‘using a ВЕ. VTVM. The normal focal oscillator voltage is One or two volts (rms) at the tuning
capacitor, depending on the tuning capacitor positon. If the focal oscillator voltage is normal,
next check all voltage distribution in the FM Front End and IF amplifier unit and compare them
| with those shown in the circuit diagram. When both meters detlect but no sound 15 obtained,
- ‚check audio circuits, using high sensitive oscilloscope. = o 5
Symptom: No Stereo Separation: В ВД |
First check the MONO switch is in normal out position. Connect a FM ВЕ signal < generator
output modulated by a stereo modulator to the rear FM antenna terminals, and check the stereo
| beacon | is turned on or not. df not turned on, check for 19KHz ptlot signal and 38KHz switching
ВЕ Se using an oscilloscope.
_ Phono and Tone Amplifiers EEE
Program source signals from the PHONO jacks on the rear panel are supplied to the input
LS circuit of the Phono Amplifier through the selector switch and the output of the Phono
Amplifier 15 applied ! to another section of the selector switch. This amplifier provides a gain of
40dB. | о В | a
AH signals selected by + the function swit tch (5002-3F, 4F) are led to the balance and volume
controls through the MONO switch. |
Signals properly attenuated by the volume control are applied to the tone amplifier and
subi ected to the tone control networks such as bass, mid, treble control and high and low cut
filters. — и SE a a.
Thus controlled audio signals are then ed to the PRE QUT jacks on the rear panel.
Figo
5. Power Amplifier 0
The signal from the tone amplifier is applied to the differential amplifier (base of H751)
through the coupling capacitor C751. The differential amplifier provides very high input
impedance and its collector output (H752) is applied to the base of H753 which in turn applies
its output to the next stage; H756 through the network R766, C762 and R771, and to the H757
through the network R776, C763 and R772. The outputs-of H756 and H757 are applied to the
H758 and H757 respectively. HOO1 and HOOZ are power transistors used in complementary
symmetry configulation and mounted on the heat sink.
To maintain overall amplifier - stability and linearity, degenerative feed back 1s utilized
throughout the amplifier. This feed back is also necessary to reduce distortion to within specified
limit. The RC network R775 and C756 condition the feed back signal for the audio signals. R759
and C755 are also a feed back loop provided to obtain a stable zero DC off set voltage at the
speaker output terminals. The R762 is a trimming resistor to adjust the DC off set voltage.
Dynamic bias is applied to the base of driver transistors H/758 and H757. This dynamic bias
circuit is comprised of H761, H760 and R763. This provides a variable base bias for driver
transistors that ‘automatically maintains the proper base voltage with temperature change. The
temperature sensitive biasing components of the dynamic circuit are thermally couppled through
a heatsink to the power amplifier transistors.
Power Protection Circuit
— Protection circuit for the amplifier is provided by s sensing resistor networks and two switching
. transistors. When the output transistors are over-driven, the current increase through the power
| output transistor causes an increased curreñt flow through R789 (or R788) and the potential
“across the: R789 will be increased. This increased voltage potential is applied to the base’ of H755
| through the resistor R783 and turns on the H755. Since the collector of. H755 is directly
connected to the base of H757, this means that the base of H757 1s bypassed 10 the ground
“through emitter-collector path of H755. Thus the input signal to the H757 is restricted to the
“value which maintains the operation of power transistor with in the safety area. A resistor
‘ “network R777 and R781 also works as a sensing network. When the center voltage (collector
= voltage of power t transistors) ÍS excessively increased to a positive value by certain troubles, the
voltage applied to the base of H755 makes the H755 turn on, making bypass circuit, and protects
“the power transistor, For the other half cycle of driving signal, the operating principle is applied
| provided. | a o
Speaker Protector Relay Circuit -
“The speaker protection circuit consisting of H808, Н809, HB10, etc protects the speaker
“systems against any loud “pop” “ sound developed. This circuit is so designed that no sound 15°
heard for the first three or five seconds after the power switch is turned on by the time constant
circuit consisting of C807 and R816. This circuit also protects the speaker systems against some
troubles due to DC off balance between the speaker system terminals by instantly operating the
relay and cut off the speaker systems from the circuit. When DC off balance voltage (positive) 15.
developed between speaker terminals by possible defects such as broken power transistor,
short-circuits, or broken potentio meter R762, as the base of H808 is connected to the speaker
terminal, the transistor H808 15 turned on by this offset voltage developed and this makes the
transistor H809 and H810 turns off, thus cutting off the relay and disconnecting the speaker
from the output circuit. When negative offset voltage is developed, this voltage directly turns off
“the H809 and H810, thus speaker is cut off from the circuit and protected. a
The circuit also protects the speaker systems from the possible damage when the amplifier | 15
over-driven by very Low frequencies such as 7 or lower cycles. o |

. Set the FM SG to 108.5 MHz and provide about 3 to 59 uV output. Rotate the tuning knob and
place the tuning pointer at the high frequency end and adjust the tr imming capacitor | C106 for
maximum output.
Repeat the step 2 and 3 until no further adjustment is necessary.
Set the FM SG 5 90 MHz and tune the receiver to the same frequency. Decrease signal
generator output until the audio output level decreases with the decreasing generator output.
| Adjust the antenna. coil L101, RF coil. L102, L103 and IF transformer L105 for
minimum audio distorti on.
. Set the FM 5G to 106 MHz and tt tune the receiver to ‘the same frequency. Adjust the trimming
capacitor Ci02, C104- and C105 for minimum distortion.
. Adjt ist the secondary core (black) of discriminato r transformer L501 so that the center tuni ng
e
meter pointer indicates its center at no signal applied. Set the FM SG to 98 MHz and increas
its output level to TK pV and tune the receiver to the same frequency so that the center tuning
meter pointer indicates its center. Adjust 1 the primary core (pink) of L501 for minimum
distortion. | o
13. STEREO ) Separation Alignment

3.
Set the FM SG to provide 1 kuV at 98 MHz. Tune the rec er lo the same frequency so that
the center tuning meter. pointer indicates | its center. | |
Modulate the FM 5С with stereo composite signa || consisting of only subchannel signal (of
course a pilot signal must be included). Adjust the core of 1301 for maximum au: dio outpui,
then, modulate the signal generator with ä stereo composite signal consisting of only L chanrel В
signal and again adjust the core of L301 for maximum audio output.
Adjust the trimming resistor R365 for maximum and. same separation in both channels,
oh
14. Muting Circuit t Alignment
1. Connect a VTVM across the resistor R022 and adjust the resistor R022 until the meter reads
0.75 V DC at no signal.
2. Set the FM SG to provide 1 KuV at 98 MHz and tune the receiver to the same frequency
correctly.
3. Turn on MUTING pushswitch. Shift the FM signal generator frequency to plus and minus and
note both plus and minus shifted frequencies at which undesirable audio side responses are
muted out. Adjust the RO22 so that the same shifted frequencies mute the undesirable side
response. |
15. Audio Adjustment
1. Voltage adjustment
Connect a DC voltmeter between pin terminal. J802 and J803, and adjust the trimming
resistor R809 for 35V DC.
2. Main Amplifier DC off-set alignment
Connect a DC voltmeter with 0.5 or 1V range between the speaker terminals and adjust the
trimming resistor R762 for “zero” DC output on the meter.
Repeat the same procedure for the other channel. |
Note: During this alignment no load should be ‚connected to the speaker terminals.
3. Idie-current adjustment о |
Connect a VTVM between pin terminals 1753 and J754. Next, rotate the trimming resistor
‘R763 fully counterclockwise, then rotate it clockwise again until the VTVM reads 5mV DC.
Repeat the same procedure for the other channel. | | 0
4, Check DC off-set voltage aligned in the procedure 2 and if any DC output 15 observed onthe
DC voltmeter, adjust the R762 again for‘ ‘Zero’ output.
5. Phono- amplifier adjustment . Ш |
Connect a oscilloscope to the TAPE OUT j jacks and an audio signal generator to the PHONO
jacks. Place the selector switch in the PHONO position. Increase 1KHz audio signal gradually
until. a slight clipping on top of the sine- wave is observed on the oscilloscope. Adjust the
trimming resistor R708 for equal cli ipping level. | |
For the other channel adjust R709. В
6. Main Amplifier. ASO adj ustment
‘For this alignment two DC oscilloscopes are > necessary.
6.1 First, make calibration on each oscilloscope gain for; .-
Vertical Sensitivity 0.2 V/em
Horizontal Sensitivity 10 V/em
6.2 Connect pin J753 to the scope vertical! input terminal. Connect pin J/56 to the SCOPE
horizontal input terminal. Adjust the horizontal and vertical position knobs so that a’ spot
on the scope IS placed on the lower right corner.
6.3 Connect pin 3760 to the scope vertical input terminal. Connect pin J761 to the scope ground
terminal. Connect pin J756 to the scope horizontal input terminal. Adjust the horizontal and
vertical position knobs so that a “spot” on the scope is placed on the lower left corner.
6.4 Remove two jumper plugs connected between the PRE QUT and MAIN IN jacks on the ear
panel. Connect a low loss oil paper capacitor « ot 1 OF (or equivalent) to the speaker terminals
being adjusted. | Е
6.5 Connect an audio > signal generator to the MAIN IN jack. Increase the audio signal {(1KH z)
input level until the Lissajou Figures as shown below are obtained on the scopes. Adjustt he
trimming resistors R782 and R783 for the height of 2. 5cm,
6.6 Change | the audio input frequency from TKHz to 20Hz and check whether the speicer
del
protection relay has been operated or not. (When the relay has been operated, no signal is
provided to the speaker terminals.) If there is no signal at the speaker terminals, turn off the
system power of the amplifier for about one minutes, then again turn on the power and
adjust the R782 and R783 for a slight increased height of A and B.
6.7 For the another Main Amplifier, repeat the procedures 6. 2 to 6.6.
