3. CIRCUIT DESCRIPTION
Fis. 5
o Equalizer Amplifier Section
This unit consists of a 2-stage direct-coupled
amplifier. Q101, Q102 2-stage direct-coupled
amplifier becomes NAB equalizer for a TAPE
playback.
o Tone Control Section
A signal from the volume control section is
conveyed to this tone control section. Two
separate controls of bass and treble, adopting
CR type tone control in its circuit, adjust the
tone and conpensate it to optimum quality.
o Volume Control Section
This unit consists of 2-stage amplifier, volume
and balance controls. The volume control ad-
justs voiume level of any selected incoming
source signal and the balance control adjusts
uneven volume level in right and left channels.
o Main Amplifier Section
The signal from the previous stage tone control
section is delivered to this 4-transistor main
amplifier section. The output stage, consists
of 2 transistors, amplifies total of 8 watts
maximum output power covering the frequen-
cies from 20 to 15,000H2 in less than 5%
total harmonic distortion.

(Balanced )BAR
ANTENNA
o FM Section
The selected FM broadcast signal, received at
the antenna, is tuned in a tuning circuit consist-
ing of inductance L I and a variable capacitor;
after amplification in RF amplifier Q I the
signal is passed to the next tuning circuit, a
variable capacitor and inductance L2. In these
two stages, the sensitivity of spurious signals is
drastically suppressed, so as to improve image
rejection ratio and overall spurious rejection
ratio. The signal is then inserted to mixer amp-
lifier Q2. This signal produce an output from
the mixer which is the intermediate frequency
signal. This IF signal (10.7MH2) is gained
through IFT T1 (intermediate frequency trans-
former) and then amplified by IF amplifier
circuit consisting of I transistor and 1 IC.
The IF amplifier includes 2 high-selectivity
ceramic filters which afford an extremely steep
cut attenuation of frequencies outside the IF
band, and guarantees selectivity in excess of
50dB between signals, assuring no possibility of
interference from adjacent broadcasting stations.
The IF amplifier also includes limiting, such
that upon reaching a certain value, signals are
not further amplified, so that the output is
constant. By virtue of the limiter effect, the
capture ratio is held to not more than 1.5, and
interference between broadcasting stations of
the same frequency is greatly reduced. Follow-
ing the IF stages, the signal is detected in the
frequency discriminator consisting of T2, T3,
D3 and D4, from which the audio frequency
modulation is derived. The recovered signal is
decoded by the MPX (multiplex) decoder and
separated into stereo right and left channel

signals. The MPX circuit employs a monolithic
IC, ensuring a high level of performance and
reliability.
o About the PLL (Phase Lock Loop)
This unit is adopting in its MPX circuit, a PLL
system, which utilizes no coils and capacitors
that are changeable of their characteristics. PLL
is a kind of electronic closed-loop servo system
and has a electronic control device to detect
and control phase variations automatically. PLL
functionates in very stable to the specified
tolerance and separation factor and maintains
MPX circuit in constant condition.
o AM Section
The selected AM broadcast signal received at
the ferrite bar antenna is mixed with the local
oscillator output (L6) in the mixer amplifier
IC 1. The output of this stage, the intermediate
frequency signal, is passed to T4 which consists
of a matching transformer and a ceramic filter
of high sensitivity, ensuring good band width
and adequate selectivity. The IF signal is pro-
cessed through 2 stages of amplification in IC I
which are common to the FM section. The
amplified IF signal then passes to the AM
detector consisting of T5 and D5 where the
audio signal component is recovered. At this
point the AGC is taken off and feedback
through a network, to control IC 1. By this
means the audio level is maintained constant,
against variations of antenna signal strength.
