CIRCUIT

DESCRIPTION

This

is

a

highly

1C-ed

pre-main-amplifier

with

OCL

(Output

Capacitor

Less)

amplifier.

It

consists

of

equalizer

amplifier,

tone

control

unit,

main

amplifier

protection

circuit

and

power

supplier.

Followings

are

explanation

about

each

circuitry

and

its

operation.

1.

MAIN

AMPLIFIER

The

main

amplifier

consists

of

driver

IC

and

power

transistor.

The

driver

IC

is

specifically

designed

to

drive

the

power

transistor

and

the

internal

current

limitter

to

protect

the

output

power

transistor

from

accidental

shortcircuit

or

overload,

being

workable

on

either

single

or

split

power

supply.

The

equivalent

circuit

of

this

IC

is

as

shown

in

Fig.

3.

Principle

Circuit

Ee

Tae

Referring

to

the

equivalent

circuit

in

Fig.

3

and

the

principle

circuit

in

Fig.

4,

we

explain

the

operation

of

the

circuit.

The

input

signal

is

applied

in

between

K313

and

earth

and

then

to

the

8

via

the

C301.

The

Q1

and

Q2?2

serve

as

differential

amplifier,

which

works

to

connect

the

signal

given

with

the

single

power

supply

(from

the

with

the

amplifier

operated

on

the

split

power

supply.

The

Q3,

D1

and

D2

form

constant

voltage

circuit.

The

signal,

which

is

differencial-amplified

in

the

Q1,

is

supplied

to

the

base

of

Q4

via

the

PIN7

.

The

D6

~

D8,

connected

to

the

collector

of

Q4,

give

an

appropriate

bias

to

the

and

also

supply

thereto

the

balanced

signal

with

the

earth

positioned

at

the

center.

The

Q11

is

NPN

transistor.

These

PNP

and

NPN

transistors

form

complementary

circuit.

Therefore,

the

upper

half

of

waveform

is

amplified

at

the

Q401

via

the

2

and

the

lower

half

amplified

at

the

Q403

via

the

13

,

which

then

appear

in

the

K313

as

output

waveform.

Since

the

DC

voltage

of

K313

is

of

OV,

it

is

not

needed

to

use

the

coupling

capacitor

conventionally

employed

in

the

SEPP

type

amplifier.

(The

name

of

OCL

is

derived

from

this

fact.)

The

Q15

works

to

filter

the

ripple

of

+B

if

the

capacitor

is

inserted

to

the

4

.

The

Q11

and

Q13

form

current

limitter.

If

an

abnormal

current

runs

in

the

Q401

and

Q403,

DC

voltage

increases

in

the

R313

and

R315

and

reaches

the

base

of

Q10

and

Q13

via

the

1

and

12

,

causing

the

signal

to

be

grounded.

The

minimum

current

required

for

operating

this

protection

circuit

can

be

adjusted

by

the

values

of

the

R309

and

R311.

The

R305

is

a

resistor

to

determine

the

negative

feedback

amount.

With

the

R305

lessened,

the

nagative

feedback

amount

decreases,

thus

increasing

the

gain

of

the

maplifier.

To

the

6

and

7

is

connected

the

capacitor

for

preventing

the

oscillation.

The

OCL

amplifier

is

an

ideal

amplifier.

from

the

following

points;

Its

low

frequency

response

characteristic

is

superior

in

particular

because

of

the

absence

of

the

coupling

capacitor,

and

flat

reproduction

is

assured

up

to

as

low

as

10Hz

in

the

case

of

main

amplifier

alone.

In

addition,

negative

feedback

is

sufficiently

applied

due

to

the

IC

driver

to

remarkably

lessen

the

distortion.

Equivalent

Circuit

Fig.

Equalizer

Amplifier

Explained

here

is

the

operation

of

this

circuit.

The

internal

equivalent

circuit

of

the

IC201

is

of

directcoupled

3-stage

amplifier.

The

first

stage

Q1

serves

as

grounded

emitter

circuit

and

the

input

signal,

coming

via

the

K202,

is

amplified

at

the

base

of

QI

and

then

appears

in

the

collector.

In

order

to

increase

the

collector

load

of

Qi

the

second

stage

Q2

and

third

stage

Q3

are

made

an

equivalent

circuit

with

Darlington

connection,

thus

the

input

impedance

at

the

second

stage

is

increased.

The

last

stage

Q3

serves

as

grounded

emitter

circuit

and

obtains

the

output

from

the

collector.

The

bias

is

supplied

from

the

emitter

(PIN

5)

of

Q3

to

the

base

(PIN

2)

of

QI

via

the

R205.

(DC

negative

feedback

type.)

agin,

This

IC

is

developed

for

the

low

frequency

high

gain

amplifier,

of

which

the

withstand

voltage

is

higher

enabling

the

power

supply

voltage

to

increase

and

then

the

dynamic

range

is

significantly

extended.

It

is

also

manufactured

taking

the

advantage

of

PCT

system

(Perfect

Crystal

Device

Technology)

which

lessens

the

noise.

In

addition,

the

gain

of

the

first

stage

is

increased

as

the

load

resistance

of

Q1

is

made

higher

and

also

the

noise

in

the

and

on

is

limitted

to

the

minimum.

Therefore,

the

overall

noise

through

the

whole

circuit

is

fully

reduced.

The

negative

feedback

block

connected

between

the

6

and

3

works

to

determine

the

frequency

characteristic

and

gain

of

this

amplifier.

In

this

circuit

is

employed

the

parallel

CR

circuit

to

obtain

RIAA

curve

characteristic

but

if

the

pure

resistor

is

used

instead

for

this

circuit,

this

equalizer

also

serves

as

flat

amplifier.

TONE

CONTROL

UNIT

The

tone

control

unit

is

consisted

of

level

controller,

tone

control

amplifier

and

tone

controller.

The

level

controller

comprises

the

balance

control

and

volume

control.

As

to

the

balance

control

of

this

set,

MN

type

curve

rotary

variable

resistor

is

employed.

In

the

amplifier

is

applied

the

same

IC

as

that

for

the

equalizer

amplifier

described

in

the

item

3

“EQUALIZER

AMPLIFIER”.

Their

circuits

are

the

in

the

circuit

of

amplifier

is

used

pure

resistor

instead

of

PROTECTION

CIRCUIT

As

seen

from

the

item(1)

“MAIN

AMPLIFIER”,

the

protection

circuit

incorporated

in

the

1¢301

prevents

the

set

from

being

affected

by

the

overload

signal

due

to

the

shortcircuit

of

speaker

terminal,

but

the

speaker

happens

to

be

burn

out

due

to

the

employment

of

OCL

circuit

with

which

the

DC

current

may

run

directly

into

the

speaker

if

a

big

DC

voltage

is

applied

to

between

the

earth

K323

and

output

terminal

K313

or

K314

in

the

worst

case.

In

an

ordinary

state,

it

scarcely

occurs

that

DC

voltage

is

applied

to

between

the

K323

and

K313

or

K314

because

the

IC-301

or

1C302

incorporates

the

circuit

to

balance

DC.

DC

is

applied

thereto

only

when

the

1C301

(or

IC-302),

Q401

and

Q403

(or

Q402

and

Q404)

are

accidentally

destroyed.

However,

to

further

counteract

the

rare

case

above,

the

protection

circuit

formed

by

the

Q301

~

Q304

and

relay

is

additionally

provided

to

protect

the

speaker.

When

the

plus

DC

voltage

appears

in

between

the

K313

and

K323,

it is

applied

to

the

base

of

Q304

via

the

R329.

As

the

result

the

current

runs

in

the

Q304

and

its

collector

voltage

drops

more

abundantly

than

in

the

case

of

non-signal

because

of

the

R319.

The

Q302

and

Q301

are

PNP

transistors.

The

PNP

transistor

gets

conductive

when

the

base

voltage

becomes

minus

with

respect

to

the

emitter

voltage,

and

therefore

the

current

runs

in

the

Q304

and

also

in

the

Q302,

to

cut

off

the

Q301,

then

the

relay

stops

to

operate.

In

a

normal

condition,

as

soon

as

the

power

switch

is

turned

on,

the

relay

starts

to

operate

to

connect

the

amplifier

with

the

speaker.

In

an

abnormal

condition,

however,

the

relay

is

cut

off

to

protect

the

speaker

from

possible

damage.

When

the

voltage

between

the

speaker

terminals

is

plus,

the

Q303

does

not

function

but

when

it

is

minus,

the

Q303

functions

to

cut

off

the

relay

as

in

the

case

the

voltage

is

plus.

The

R329,

C315

and

C316

form

low

pass

filter

to

prevent

the

relay

being

worked

by

audio

signal.

The

relay

is

the

inductive

one

and

will

generates

reaction

voltage

if

it

is

abruptly

turned

on

or

off.

This

voltage

is

absorbed

by

the

D301,

however.

The

minimum

nubalanced

DC

voltage

to

make

the

relay

operate

is

depended

upon

the

value

of

R319

or

R327.

POWER

TRANSISTOR

REPLACEMENT

The

power

transistors

used

in

the

output

stages

are

matched

pairs.

They

have

been

selected

so

that

they

have

very

similar

current

gain

and

trans-conductance

characteristics.

This

matching

is

necessary

in

order

to

assure

optimum

perfor-

mance,

but

is

such

that

if

a

transistor

fails

in

either

channel,

another

transistor

in

that

channel

must

also

be

replaced.

Transistors

are

supplied

only

in

matched

pairs

for

replacement.

The

transistors

diffuse

a

large

amount

of

heat

which

must

be

carried

off

in

order

to

prevent

damage

to

the

transistors

the

collectors

of

which

are

thermally

connected

to

the

heat

sink

by

means

of

electrical

insulators

to

avoid

grounding.

The

insulator

is

a

very

thin

plastic

film

mounted

between

the

transistor

case

(collector)

and

the

heat

sink.

A

layer

of

silicon

grease

which

is

a

good

conductor

of

heat

is

applied

to

both

sides

of

the

insulator

in

order

to

improve

heat

sink

operation.

When

the

power

transistors

are

replaced

the

spacer

film

must

be

re-installed

and

a

new

layer

of

grease

applied

to

both

sides.

Care

should

be

taken,

lest

conductive

dust

such

as

metal

particles

should

break

through

the

insulator

films.

Q401

and

Q403,Q402

and

Q404

are

matched

pairs.
