FEATURES

@

MC

Head

Amplifier

(13

transistors

for

each

channel)

The

MC

head

amplifier

uses

a

push-pull

amplifier

in

the

first

stage

which

consists

of

4

very

low

noise

NPN

tran-

sistors

and

4

very

low

noise

PNP

transistors.

It

uses

also

push-pull

transistors

in

the

second

stage

and

an

SEPP

circuit

in

the

output

stage.

The

feedback

circuit

impedance

is

reduced

és

much

as

possible

to

improve

the

S/N

ratio,

and

a

voltage

gain

of

26

dB

(20

times)

is

obtained

at

a

rated

input

level

of

110

uV.

@

PHONO

Amplifier

(11

transistors

for

each

chamel!)

The

PHONO

amplifier

uses

full

push-pull

citcuits

con-

sisting

of

11

transistors

for

each

channel,

sc

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

channel

and

P

channel

FETs,

combined

with

a

cascode

current

Miller

circuit

so

that

degradation

of

characterisitics

of

following

crcuits

due

to

input

stage

impedance

fluctuations

is

prevented.

The

second

stage

consists

of

an

emitter

follower

buffer

amplifier

and

a

push-pull

voltage

amplifier.

The

output

stage

uses

an

SEPP

circuit

which

s

adequate

to

any

type

of

load.

The

equalizer

elements

have

very

low

impedance

compared

with

conventiona

equalizer

circuits,

so

a

S/N

ratio

of

90

dB

is

obtained

a

the

rated

input

level.

The

equalizer

elements

used

are

metal

filn

resistors

with

tolerance

of

1%

and

polypropylene

capei

tors

with

tolerances

of

2%,

so

RIAA

phono

equalizationaf

/0.2

dB

is

obtained

over

the

audio

range

from

20

Hz

to?O

kHz.

The

input

impedances

of

27

kQ,

47

kQ

and

00

kQQ

are

provided

to

allow

different

cartridges

to

be

connected

when

the

PHONO

1

input

is

selected.

The

output

stage

is

provided

with

a

relay

tc

snute

un-

desireable

noise

when

the

power

is

switched

ON

and

OFF,

and

with

an

EQ

subsonic

filter

to

reduce

turnta

#e

rumble

and

flutter

noise.

e@

TONE

Switch

The

TONE

switch

allows

the

number

of

coupling

capa-

citors

to

be

reduced

to

one

by

applying

the

PHONO

amplifier

output

signal

directly

to

the

line

amplifier

when

the

switch

is

set

to

the

TONE

OUT

position.

The

gain

and

input

sensitivity

are

not

changed

by

operating

this

switch.

TONE

OUT

HEADPHONE.

OUT

@

Line

Amplifier

The

line

amplifier

consists

of

15

transistors

for

each

channel,

and

uses

push-pull

circuits

which

operate

in

class

A

in

all

stages

to

reduce

TIM

distortion

and

im-

prove

the

S/N

ratio.

The

input

stage

uses

a

source

follower

with

dual

FETs

to

prevent

it

(the

input

stage)

from

affecting

following

stage

characteristics.

The

source

follower

output

signal

is

applied

to

the

differential

amplifier

through

dual

transistors.

One

of

the

differential

amplifier

output

signals

is

phase-

inverted,

then

both

output

signals

are

applied

to

the

second

stage

push-pull

amplifier

through

buffer

amplifiers.

The

power

amplifier

stage

uses

newly

developed,

super

high

f7

(200

—

250

MHz)

power

transistors

which

are

connected

in

a

Darlington

configuration.

This

power

amplifier

stage

operates

in

pure

class

A,

and

features

flat

frequency

response

and

low

TIM

distortion.

This

amplifier

can

drive

headphones

in

class

A

operation,

as

well

as

a

main

amplifier.
