LEAKAGE

TEST

(FOR

SERVICE

ENGINEERS

IN

THE

U.S.A.)

Before

returning

the

unit

to

the

user,

perform

the

following

safety

checks:

1.

Inspect

all

lead

dress

to

make

cer-

(

tain

that

leads

are

not

pinched

or

that

hardware

is

not

lodged

be-

tween

the

chassis

and

other

metal

parts

in

the

unit.

2.

Be

sure

that

any

protective

devices

such

as

nonmetallic

control

knobs,

insulating

fishpapers,

cabinet

backs,

adjustment

and

compartment

cov-

ers

or

isolation

§resistor-

.

capacity

networks,

mechanical

in-

€.

sulators,

etc.

which

were

removed

for

servicing

are

properly

reinstalled.

3.

Be

sure

that

no

shock

hazard

exists;

check

for

leakage

current

using

Simpson

Model

229

Leakage

Tester,

standard

equipment

item

No.

21641,

RCA

Model

WT540A

or

use

alternate

method

as

follows:

Plug

the

power

cord

directly

into

a

120-volt

AC

receptacle

(do

not

use

an

Isolation

Transformer

for

this

test).

Using

two

clip

leads,

connect

a

1500

Ohm,

10-watt

resistor

paralleled

by

a

0.15uF

capac-

itor,

in

series

with

all

exposed

metal

cabinet

parts

and

a

known

earth

ground,

such

as

a

water

pipe

or

conduit.

Use

a

VTVM

or

VOM

with

1000

Ohms

per

volt,

or

higher,

sensitivity

to

measure

the

AC

voltage

drop

across

the

resistor.

(See

Diagram.)

Move

the

resistor

connection

to

each

exposed

metal

part

having

a

return

path

to

the

chassis

(antenna,

metal,

cabinet,

screw

heads,

knobs

and

control

shafts,

escutcheon,

etc.}

and

measure

the

AC

voltage

drop

across

the

resistor.

(This

test

should

be

performed

with

the

power

switch

in

both

the

On

and

Off

positions.)

A

reading

of

0.35

volt

RMS

or

more

is

excessive

and

indicates

a

potential

shock

hazard

which

must

be

corrected

before

returning

the

unit

to

the

owner.

CIRCUIT

DESCRIPTION

(1)

SIGNAL

PATH

The

FM

signal

is

amplified

in

the

RF

amplifier

3SK74

(3SK85,

3SK101)

at

the

front

end,

then

mixed

with

the

output

of

the

local

oscillator

2SC461

(2SC930,

25C2834)

and

converted

into

a

signal

of

the

10.7MHz

intermidlate

frequency.

This

10.7MHz

signal

is

amplified

in

the

IF

amplifier

consisting

of

the

ceramic

filters

CF201

~

CF203

and

0201

~

0204

and

fed

to

@

of

1C201.

In

1C201,

the

signal

is

amplified

in

the

triple

IF

amplifiers,

and

after

being

detedted

in

the

quadrature,

it

is

put

out

from

©)

as

an

audio

signal,

which

is

then

sampled

and

holded

by

means

of

the

38kHz-

signal

produced

in

C151

and

fed

to

the

audio

amplifier.

(2)

MUTING

OPERATION

WHILE

TUNING

When

not

of

tune

or

the

signal

is

too

weak,

the

muting

control

voltage

is

taken

out

from

@

of

!C201

and

is

fed

to

the

base

of

0205,

whose

collector

then

becomes

low

level.

The

muting

signal

is

sent

to

the

muting

control

circuit.

As

0357

becomes

high

level,

the

signal

is

fed

to

NAND

1C351.

The@)pin

of

1C351

and

Q7

become

low

level

and

high

level

respectively

and

muting

gates

0317

(Lech)

and

0318

(Rch)

become

low

level,

thus

muting

operation

is

completed.
