SAFETY

CHECK-OUT

(US

MODEL

ONLY)

After

correcting

the

original

service

problem,

perform

the

following

safety

checks

before

releasing

the

set

to

the

customer:

1.

Check

the

area

of

your

repair

for

unsoldered

or

poorly-soldered

connections.

Check

the

entire

board

surface

for

solder

splashes

and

bridges.

2.

Check

the

interboard

wiring

to

ensure

that

no

wires

are

‘pinched’

or

contact

high-wattage

resistors.

3.

Check

that

all

control

knobs,

shields,

covers,

ground

straps,

and

mounting

hardware

have

been

replaced.

Be

absolutely

certain

that

you

have

replaced

all

the

insulators.

4.

Look

for

unauthorized

replacement

parts,

par-

ticularly

transistors,

that

were

installed

during

a

Point

them

out

to

the

customer

and

recommend

their

replacement.

5.

Look

for

parts

which,

though

functioning,

show

obvious

signs

of

deterioration.

Point

them

out

to

the

customer

and

recommend

their

replace-

ment.

6.

Check

the

line

cord

for

cracks

and

abrasion.

Recommend

the

replacement

of

any

such

line

cord

to

the

customer.

7.

Check

the

condition

of

the

monopole

antenna

(if

any).

Make

sure

the

end

is

not

broken

off,

and

has

the

plastic

cap

on

it.

Point

out

the

danger

of

impalement

on

a

broken

antenna

to

the

customer,

and

recommend

the

antenna’s

replacement.

8.

Check

the

B+

and

HV

to

see

they

are

at

the

values

specified.

Make

sure

your

instruments

are

accurate;

be

suspicious

of

your

HV

meter

if

sets

always

have

low

HV.

9.

Check

the

antenna

terminals,

metal

trim,

“metallized”

knobs,

screws,

and

all

other

exposed

metal

parts

for

AC

leakage.

Check

leakage

LEAKAGE

TEST

The

AC

leakage

from

any

exposed

meta!

part

to

earth

ground

and

from

all

exposed

metal

parts

to

any

exposed

metal

part

having

a

return

must

not

exceed

0.5mA

(500

microampers).

Leakage

current

can

be

measured

by

any

one

of

three

methods.

1.

A

commercial

leakage

tester,

such

as

the

Simpson

229

or

RCA

WT-540A.

Follow

the

manufacturers’

instructions

to

use

these

instru-

ments.

2.

<A

battery-operated

AC

milliammeter.

The

Data

Precision

245

digital

multimeter

is

suitable

for

this

job.

3.

Measuring

the

voltage

drop

acfoss

a

resistor

by

means

of

a

VOM

or

battery-operated

AC

volt-

meter.

The

“‘limit”

indication

is

0.75V,

so

analog

meters

must

have

an

accurate

low-

voltage

scale.

The

Simpson

250

and

Sanwa

SH-63Trd

are

examples

of

a

passive

VOM

that

is

suitable.

Nearly

all

battery

operated

digital

multimeters

that

have

a

2V

AC

range

are

suitable.

(See

Fig.

A)

HOW

TO

FIND

A

GOOD

EARTH

GROUND

A

cold-water

pipe

is

guaranteed

earth

ground;

the

cover-plate

retaining

screw

on

most

AC

outlet

boxesis

also

at

earth

ground.

If

the

retaining

screw

is

to

be

used

as

your

earth-ground,

verify

that

it

is

at

ground

by

measuring

the

resistance

between

it

and

a

cold-

water

pipe

with

an

ohmmeter.

The

reading

should

be

zero

ohms.

If

a

cold-water

pipe

is

not

accessible,

connect

a

60-100

watts

trouble

light

(not

a

neon

lamp)

between

the

hot

side

of

the

receptacle

and

the

retaining

screw.

Try

both

slots,

if

necessary,

to

locate

the

hot

side

of

the

line,

the

lamp

should

light

at

normal

brilliance

if

the

screw

is

at

ground

potential.
