ANNOUNCING...

for

the first time

A complete TV

Tube Testing

Outfit designed

specifi-

cally to

test all

TV

tubes, color as well as standard.

Don't

confuse

the Model

257 picture

tube accessory

components

with

mass

produced "picture tube

adap-

ters" designed

to work

in conjunction with

all com-

petitive tube

testers. The basic

Model 257 circuit was

modified to work

compatibly with

our picture

tube ac-

cessories

and those

components are

not sold by

us to

be

used with

other competitive

tube testers

or even

tube

testers previously produced

by us. They were

custom

designed and

produced

to work

specifically in

conjunction

with the

Model 257.

NOTICE

We

have been producing

radio,

TV

and

electronic test equipment

since 1935,

which means we were making

Tube

Testers at

a

time when

there

were relatively

few

tubes on the market,

'way

before

the advent of TV. The

model 257

employs every

design improvement

and

every

technique

we have

learned

over

an

uninterrupted

production

period

of 32 years.
