All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.
F
ATTENTION
Tous les IC et beaucoup d’autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution n’est
prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié
au même potentiel que la masse de l’appareil et
enfiler le bracelet serti d’une résistance de
sécurité.
Veiller à ce que les composants ainsi que les
outils que l’on utilise soient également à ce
potentiel.

Potential halten.
WAARSCHUWING
NL
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor electrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie kan
de levensduur drastisch doen verminderen.
Zorg ervoor dat u tijdens reparatie via een
polsband met weerstand verbonden bent met
hetzelfde potentiaal als de massa van het
apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.
I
AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevità potrebbe essere fortemente
ridatta in caso di non osservazione della più
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziale.
GB
Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in
zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,
identiek aan de gespecificeerde, worden toegepast.

PREP ARATIONS AND CONTROLS
Important notes for users in the
U.K.
Mains plug
This apparatus is fitted with an approved 13
Amp plug. To change a fuse in this type of plug
proceed as follows:
1
Remove fuse cover and fuse.
2
Fix new fuse which should be a BS1362 5 Amp,
A.S.T.A. or BSI approved type.
3
Refit the fuse cover.
If the fitted plug is not suitable for your socket
outlets, it should be cut off and an appropriate
plug fitted in its place.
If the mains plug contains a fuse, this should
have a value of 5 Amp. If a plug without a fuse
is used, the fuse at the distribution board
should not be greater than 5 Amp.
Note: These vered plug must be disposed of to
avoid a possible shock hazard should it be
inserted into a 13 Amp socket elsewhere.
How to connect a plug
The wires in the mains lead are coloured with
the following code: blue = neutral (N),
brown = live (L).
¶ As these colours ma y not cor respond with the
colour mar kings identifying the terminals in
your plug, proceed as follows:
– Connect the blue wire to the terminal
marked N or coloured black.
– Connect the brown wire to the terminal
marked L or coloured red.
– Do not connect either wire to the earth
terminal in the plug, marked E (or e) or
coloured green (or green and yellow).
Before replacing the plug cover, make certain
that the cord grip is clamped over the sheath
of the lead - not simply over the two wires.

Repair Hints
3-33-3
3) During repair it is possible to disconnect the Tuner board
and CDC Module completely unless the fault is suspected to be in that area. This will not affect the
performance of the rest of the set.
4) Due to the short flex cable wires in the ETF Module, the
pc board should be disconnected and reconnected on
the reverse side of the tape mechanism to keep it
electrically connected during repair. See picture 3.
Note: The flex cables are very fragile, care should be taken
not to damage them during repair. After repair, be
very sure that the flex cables are inserted properly
into the flex sockets before encasing, otherwise faults
may occurs.

Error Description
Focus Error
Triggered when the focus could not be found within a certain time when starting up the CD
or when the focus is lost for a certain time during play.
Radial Error
Triggered when the radial servo is off-track for a certain time during play.
Sledge In Error
The sledge did not reach its inner position (inner-switch is still close) before approximately
6 Sec. have passed by. Inner-switch or sledge motor problem.
Sledge Out Error
The sledge did not come out of its inner position (inner-switch is still open) before approximately
250 mSec. have passed by. Inner-switch or sledge motor problem.
Jump-offtrack error
Triggered in normal play when the jump destination could not be found within a certain time.
When this error occurred, software will try to recover by initiating the jump command again.
If it is recoverable, the disc will continue to play.
Subcode Error
Triggered when a new subcode was missing for a certain time during play.
PLL Error
The Phase Lock Loop could not lock within a certain time.
Turntable Motor Error
Generated when the CD could not reached 75% of speed during startup within a certain time.
Discmotor problem.
Focus Search Error
The focus point has not been found within a certain time.
The carousel switch is not open within certain time. This can happen when either the switch is
defective and closed all the time, or when the carousel is blocked when located exactly at a
disc position.
The carousel position switch did not close within a certain time. This can happen when the
switch is defective and never closes electrically, or when the carousel is blocked in between
two disc positions. The time-out is approximately 5 Sec.
The drawer could not enter the inside position is opening again. This can be caused because
the drawer is blocked by something and cannot go fully inside, or the drawer switch is defective

Brief introduction
General
1.Playback Mode
Signal from the playback head Deck A or Deck B is selected and fed through by the Mode Selector IC7710 (HEF4952BT).
The signal is amplified by amplifier IC7720 (AN7323S) before feeding to the IC7740 (HEF4952BT) and out to the AF Board
via connector 1701.
9-3
Motor Speed (For FR versions only)
13.
During High speed dubbing, a feedback signal from the uP through pin 03 of the IC7610 (HEF4094BT) will trigger the
transistors 7622 (BC847B) and 7616 (BC857B) to cause a change in the voltage level between High and Low, thus changing
the speed of the motor.
2.Recording Mode
Recording Signal is selected and fed through by the Mode Selector IC7710 (HEF4952BT) which is then amplified by the
amplifier IC7720 (AN7323S). The amplified output signal will pass through IC7730 (HEF4952BT) for record equalization and
back to IC7710 (HEF4952BT) before registered into the Rec/PB Head of Deck B.
3.Dubbing Mode
In Dubbing mode, signal from the playback head Deck A is selected and fed through by the Mode Selector IC7710
(HEF4952BT) which is then equalised for playback mode by the amplifier IC7720 (AN7323S) so that a flat response is
obtained after the pre-amp. The equalised signal will then follow the same path as in the Recording mode.
4.Mode Selector
The Mode Selector IC7710 (HEF4952BT) caters for 4 inputs signal, namely Playback Signal from Deck A, Playback Signal
from Deck B, Recording Signal and Dubbing Signal.
Amplifier PB/REC
5.
Amplifier IC7720 (AN7323S) is for the purpose of amplifying the Playback and Recording signal from the Mode Selector.
6.Automatic Level Control (ALC)
ALC circuit consists of resistors (3760, 3765, 3766, 3767), capacitors (2762 , 2763) and control by transistor 7787 (BC847B).
ALC limits the amplifier output to a constant value when input signal becomes too large, thus limiting recording current to
below saturation level, to prevent recording distortion.
7.
Muting Circuit (For Non-Dolby version only)
Switch S4 of the IC7740 (HEF4952BT) is for the purpose of muting the output during Recording mode. During Recording
mode, S4 is closed and shorted to the ground.
8.IC7740 (HEF4952BT)
The function of the IC7740 (HEF4952BT) is to change time constant between 120us Ferro (IEC I) and 70us Chrome (IEC
II) during playback mode. It will automatically determined whether the tape type is 120us Ferro (IEC I) or 70us Chrome (IEC
II). This IC will switch to Flat Gain during the Recording mode.
IC7730 (HEF4952BT)
9.
The function of the IC7730 (HEF4952BT) is to change gain and time constant according to tape type and recording speed
to boost recording current at higher frequency during recording to compensate for head loss. It will automatically determined
whether the tape type is 120us Ferro (IEC I ) or 70us Chrome (IEC II).
10. Bias Level
Bias Level making use of the V ariable resistor (3773) for adjusting the optimal level of the bias current for Ferro or Chrome.
11. Bias Symm (For Dolby B NR version only)
Bias Symm making use of the Variable resistor (3785) to adjust the bias current for the left and the right channel to be equal.
12. PB Switch
Playback Switch which consists of the FET s 7785 (For Dolby B NR version only) & 7786 (J1 11) is for the purpose of providing
a virtual ground for the Rec/PB Head (Deck B) during Playback mode. During the Playback mode, the FET s are turn on and
shorted pin 2 and 4 of connector 1720 to the ground. During Recording mode, the FETs are turn off to allow the oscillator
signal to be superposition onto the Recording signal for recording.
14. IC7610 (HEF4094BT)
IC7610 (HEF4094BT) is a Shift Register use for issues the logic for cmos switch ICs (HEF4952BT) via 1A0, 2A1 and 2A2.
It also issues logic to On/Off SOL_A, SOL_B and MOT. Recording speed is controlled via NS/HS.
Dolby Circuit (For sets with Dolby B NR version only)
15. IC7630 (CXA1551M)
IC7630 (CXA1551M) in the Dolby circuit is a Dolby Noise Reduction Type B IC for the Playback and Recording signal. Noise
Reduction ON/OFF are controlled by DOLBY , which is from CLK, direct from uP. After clocking in DA T A, CLK is set to HIGH/
LOW for NR OFF/ON.
16. 19kHz Filter
The 19kHz filters 5631 & 5632 (LXD-210) in the Dolby circuit is for the purpose of filtering the 19kHz Pilot Tone (for Tuner
signal only) of the Recording signal.
17. Level Adjust
The Variable resistor 3635, 3636,3641 and 3642 in the Dolby circuit is for adjusting the playback level of the Dolby reference
(400Hz , 200nWb/m). Transistor 7631, 7632 are ON to enable adjustment of 3641, 3642 during Playback Deck A. T ransistor
7633, 7634 and 3635, 3636 are active for Playback Deck B.
18. Amplifier IC7640 (NJM4560M)
The Amplifiers 7640A & 7640B (NJM4560M) in the Dolby circuit is for the purpose of amplified the Recording signal.
19. Muting Circuit
The muting circuit which consists of transistors 7788, 7789 and 7790 (BC847B) is for the purpose of muting the output during
Recording mode.

via connector 1701.
Recording Mode
2.
Recording Signal is selected and fed through by the Mode Selector IC7710 (HEF4952BT) which is then amplified by the
amplifier IC7720 (AN7323S). The amplified output signal will pass through IC7730 (HEF4952BT) for record equalization and
back to IC7710 (HEF4952BT) before registered into the Rec/PB Head of Deck B.
3.
Dubbing Mode
In Dubbing mode, signal from the playback head Deck A is selected and fed through by the Mode Selector IC7710
(HEF4952BT) which is then equalised for playback mode by the amplifier IC7720 (AN7323S) so that a flat response is
obtained after the pre-amp. The equalised signal will then follow the same path as in the Recording mode.
Mode Selector
4.
The Mode Selector IC7710 (HEF4952BT) caters for 4 inputs signal, namely Playback Signal from Deck A, Playback Signal
from Deck B, Recording Signal and Dubbing Signal.
Amplifier PB/REC
5.
Amplifier IC7720 (AN7323S) is for the purpose of amplifying the Playback and Recording signal from the Mode Selector.

Attention: In the POWER 2001 module the power amplifier IC AN7591 is used as a bridge-amplifier.
Any connection from output to ground will destroy the outpout stages!
• Via the AMP_ON control line, connected to pins 6 (Stby), the power amplifiers are switched on/off by the µP.
High level (approx. 4,5V): power amplifiers switched on
Low level (approx. 0V): power amplifiers switched off
• Super class G - operation
The power amplifiers operate as so-called super class G - amplifiers:
The supply pins 12 (Vcc) are not just connected to one fixed DC-supply as in conventional amplifiers.
Dependent on the output power there are three different DC-voltages supplied to the power amplifiers:
⇒ +C1 (+20V) for low output power
⇒ +B1 (+29V) for medium output power
⇒ +A1 (+41V for high output power

POWER 2001 Module
(30 - 70W Version)
Circuit details continued:
• Low power standby feature
An additional small standby transformer, reduces power consumption in standby-mode.
In case power is switched on, the control line ECO is low → relay 1210 is activated → contacts 1 and 2 are closed →
transformer 5001is connected to mains.
When the set is switched off (standby) the control line ECO is high → relay 1210 is not activated → mainstransformer is
disconnected. Via standby transformer and rectifiers 6210-6214 the supply voltage LOW_PWR_SUP is substituted. This
voltage is always available and so the microprocessor is kept running.
• DC voltages +A1, +B1, +C1
These voltages supply the Super Class G amplifier, described on previous page.
The whole power supply is optimized for the special characteristic of this type of amplifier. For that reason several “tricky”
details have been applied to ensure optimal efficiency and symmetrical load to the mains transformer.
Generation of +A1
Common full wave rectifying with bridge rectifier 6202, using 100% secondary winding of mains transformer (pin 10-14).
Generation of +B1
The supply for +B1 consists of one full wave rectifier:
– 2 diodes of bridge rectifier 6202, with 6200(6220 in parallel) 6201(6221 in parallel) for generation of +B1using approx.
70% secondary winding of mains transformer (pin 10-13 respectively pin 11-14).
As example for generation of +B1 see picture 1.
Generation of +C1
Full wave rectifying with 2 diodes of bridge rectifier 6202, using 50% secondary winding of mains transformer (pin 13-15/13-11).
See picture 2 below.

The AF9 Board consists of the following features :
a. TDA7468D IC
TDA7468D IC (7501) which includes functions such as source selection, loudness control, dynamic bass control, treble
control, volume control and muting function. Sound features such as ALC, DBB, DSC and IS are controllable via I2C Bus
from the microprocessor.
The TDA7468D IC caters for 4 input sources namely TUNER, TAPE, CD and AUX. It also has a Mic mix input. In our
application, software will switch the input source to previous source MUTE during STANDBY mode and some other
occasions where noise from other input source is undesirable.
