MAIN
AMPLIFIER
INTRODUCTION
This service manual was prepared for use by Authorized
Warranty
Staions
and
contains
service
information
for
the
Marantz Model Pm-6a Stereo Pre Main Amplifier.
Servicing
information
and
voltage
data
included
in
this
manual
are
intended
for
use
by
knowledgeable
and
ex-
perienced
personnel
only.
All
instructions
should
be
read
carefully.
No
attempt
should
be
made
to
proceed
without
a
good
understanding
of
circuitry
operation.
The parts list furnishes complete ordering information. Most
replacement parts should: be ordered from the Marantz
Company. However, a simple description is included for
parts which can be obtained locally.

1. FEATURES
@ MC Head Amplifier (13 transistors for each channel)
The
first
stage
of
the
MC
head
amplifier
is
a
push-pull
amplifier
consisting
of
4
very
low
noise
NPN
transistors
and
4
very
low
noise
PNP
transistors.
The
second
stage
is
also
a
push
pull
amplifier,
and
the
output
stage
is
a
SEPP
amplifier.
The
feedback
circuit
impedance
is
reduced
as
much
as
possible
to
improve
the
S/N
ratio,
and
a
voltage
gain
of
20
dB
(10
times)
is
obtained
at
a
rated
input
level
of
125
uV.
@ PHONO Amplifier (11 transistors for each channel)
The
PHONO
amplifier
uses
a
full
push-pull
circuit
con-
sisting
of
11
transistors
for
each
channel
so
that
low
TIM
distortion
and
a
high
S/N
ratio
are
obtained.
The
first
stage
is
a
push-pull
circuit
consisting
of
very
low
noise,
high
Gm
N
and
P
channel
FETs
combined
with
a
cascode
current
Miller
circuit
so
that
degradation
of
following
stage
characteristics
due
to
input
stage
im-
pedance
fluctuation
is
prevented.
The
second
stage
consists
of
an
emitter
follower
buffer
amplifier
and
a push-pull
voltage
amplifier.
The
output
stage
uses
a
SEPP
circuit
which
is
adequate
to
drive
any
type
of
load.
The
equalizer
elements
have
very
low
impedances
compared
with
conventional
circuits
so
a
S/N
ratio
of
90
dB
is
obtained
at
the
rated
input
level.
The
equalizer
elements
are
metal
film
resistors
with
tolerances
of
1%
and
polypropylene
capacitors
with
tolerances
of
2%;
this
makes
it
possible
to
obtaine
an
RIAA
phono
equalization
of
+0.2
dB
over
the
audio
range
from
20
Hz
—
20
kHz.

Input
impedances
27
kQ,
47
kQ
and
100
kQ
are
provided
for
different
types
of cartridges
when
the
PHONO
1
input
is
selected.
The
PHONO
amplifier
output
circuit
is
provided
with
a
relay
to
mute
undesirable
noise
when
the
power
is
switched
ON
and
OFF,
and
with
a
EQ
subsonic
filter
to
reduce
turntable
rumble
and
flutter.
Quarter A System
The
quarter
A
system
automatically
switches
the
bias
current
and
supply
voltage
to
the
main
amplifier
by
de-
tecting
the
main
amplifier
input
voltage
and
speaker
current;
thus,
the
main
amplifier
operates
in
class
A
when
the
power
output
is
up
to
30W/8Q,
and
in
class
AB
when
the
power
output
exceeds
that
level.
The phase correction circuit in the detection circuit
prevents distortion from being generated even if a wave-
form with a sharp rising edge is applied.
Marantz’s
usual
superb
amplifier
circuit
has
not
been
altered
in
this
system,
except
that
the
detection
circuit
is
connected
to
the
signal
system.
Voltage amplifier
The input circuit of the voltage amplifier is a source
follower using a pair of FETs, so variation in the im-
pedance of this stage does not influence following stage
characteristics. The next circuit is a differential amplifier
using a dual transistor, followed by an active balance
loading circuit using a dual transistor.
One of the differential amplifier output signals is phase-
inverted, then both signals are applied to the push-pull
amplifier through the emitter follower buffer.
Power amplifier
The power amplifier employs triple Darlington connection
and supper high f— power transistors connected in paral-
lel.
The power amplifier uses unique push-pull circuit with ex-
cellent open loop characteristics and a 2-pole phase com-
pensation circuit, so the frequency response is flat even at
high frequencies and TIM distortion is reduced remark-
ably,
Other features
The speaker protection circuit uses a high performance
IC
and
relay.
The
power
supply
circuit
uses
a
large
trans-
former with high regulation and newly developed, large
capacity custom electrolytic capacitors.
To obtain continuous high power output, high efficiency
heat pipes are used to radiate the heat produced by the
power transistors.
