BRIEF

DESCRIPTION

MODEL

667

SOLID

STATE

TUBE

TESTER

The

B&K

Model

667

is a versatile,

up-to-date,

completely

solid

state,

portable tube tester that will test all tubes commonly

used in today's elec-

tronic

industry,

including

many

foreign

tube

types.

The

following tests are made

on each tube:

1.) Shorts and leakage between

any element

and all other elements,

with

a sensitivity

of 1 megohm.

Because

of exclusive

"multiple

lockout

switch"

all modern

tubes

which

have

than

one

pin connected

to the same

element

can still be completely

tested

for shorts

from

cach element

to every other element.

2.) Quality is checked in a test circuit that determines the full capability

of cathode emission

under

current

loads and voltages simulating

actual operating conditions.

Grid

emission,

gas, grid contamination,

or obscure

grid

to cathode

leakage are all disclosed

by an exceptionally

sensitive grid current

check.

This test will indicate with less than 1 microampere of grid

current.

'Phis

tester

incorporates

the casy-to-use

lockout

pushbuttons

to increase

testing capability and

prevent obsolescence

and

a special

tube chart display

holder

to facilitate rapid, error-[ree

testing.

The

tester is housed

in a highly

attractive, weatherproof,

very durable,

VIP/Attache-type carrying case.
