PROFESSIONAL OSCILLOSCOPE KIT
Everything you could possibly want in an oscilloscope is found in the
new Heathkit model OP -I. Featured are DC coupled amplifiers and
also DC coupled CR tube un- blanking. The triggered sweep circuit
will operate on either internal or external signals and may be either
AC or DC coupled. The polarity of the triggering signal may also be
selected, and any point on the waveform may be selected for the start
of the sweep by using the "triggering level" control. An automatic
position is also provided, in which the sweep recurs at 50 cycle rate,
but can be driven over a wide range of frequencies with no additional
adjustment. Prewired terminal boards are used for rapid, easy assembly
of all critical circuits. Power supply is transformer operated utilizing
silicon diode rectifiers and is fused for protection. Handsome
cabinet features silver anodized front panel with red and black
lettering and matching knobs. Shpg. Wt. 34 lbs.
VARIABLE VOLTAGE
REGULATED POWER
SUPPLY KIT
Invaluable in experimental and
design work, the PS -4 eliminates
the need for building up a separate
power supply for each new
circuit tried. It provides a convenient
source of variable regulated
B+, variable bias voltage
and filament voltage for labs and
work shops. The PS -4 supplies
regulated Bt output continuously
variable from 0 to 400 volts DC
at up to 100 ma, bias voltage variable
from 0 to -100 volts DC at
I ma, and filament voltage of 6.3
volts AC at 4 amps. Separate
panel meters continuously monitors
voltage and current output.
Rugged, top -rated components
used throughout for long, reliable
service. Shpg. Wt. 16 lbs.
TEST OSCILLATOR KIT
Provides the test frequencies most
often used by servicemen in repairing
and aligning modern
broadcast receivers. Five fixed -
tuned frequencies (262 kc, 455 kc,
465 kc, 600 kc and 1400 kc) are
quickly selected for troubleshooting
or alignment of the IF frequency
and high and low end of
the broadcast band for proper
tracking. Shpg. Wt. 4 lbs.
HEATH COMPANY

"EXTRA DUTY" 5"
OSCILLOSCOPE KIT
Laboratory quality at utility scope price
makes this instrument an unusual value.
The Heath patented sweep circuit functions
from 10 CPS to better than 500 kc in
five steps. giving you five times the usual
sweep obtained in other scopes. Vertical
frequency response extends from 3 CPS
to 5 me +1.5 db -5 db without extra
switching. An automatic sync circuit with
self -limiting cathode follower provides
excellent linearity and lock -in characteristics.
Extremely short retrace time and
efficient blanking action are characteristic
of this scope. Frequency response of the
horizontal amplifier is within *I db from
I CPS to 200 kc. Horizontal sensitivity is
0.3 volts RMS- per -inch. Construction is
simplified through the use of two etched
metal circuit boards and precut, cabled
wiring harness. Complete step -by -step
.instructions and large pictorial diagrams
are supplied for easy assembly. An ideal
scope for all service applications as well
as in standard or color TV servicing.

MODEL SG -8 $1950
RF SIGNAL
GENERATOR KIT
A "must" for any beginning serviceman,
this indispensable instrument
is used for aligning tuned
circuits quickly and tracing signals
in faulty RF, IF and audio circuits.
Covers 160 kc to 110 me on
fundamentals in five bands and
from 110 me to t20 me on calibrated
harmonics. Coils are pre -
wound and calibrated. Complete
with output cable and instructions.
Shpg. Wt. 8 lbs.
MODEL AG -9A $3450
AUDIO SIGNAL
GENERATOR KIT
This unique generator uses three
rotary switches to select two
significant figures and a multiplier
to determine audio frequency,
allowing return to the
exact frequency previously measured
when making multiple frequency
measurements. Covers
10 CPS to 120 kc with less than
.1 of 11-, distortion between 20
and 20,000 CPS. Shpg. Wt. 10
lbs.
MODEL TS -4A $4950
TV ALIGNMENT
GENERATOR KIT
TV service technicians will appreciate
the outstanding features
found in this sweep generator.
Provides essential facilities for
aligning FM, monochrome TV
or color TV sets. The all -electronic
sweep circuit employs a
trouble -free controllable inductor
which varies frequency by
magnetic means. An unusual
buy at this low price. Shpg. Wt.
16 lbs.
MODEL CD -1 $5995
COLOR BAR AND
DOT GENERATOZ
The CD- I combines the two
basic color servicing instruments,
a color bar and white dot
generator in one versatile and
portable unit, which has crystal
controlled accuracy and stability
for steady lock -in patterns.
(Requires no external sync
leads.) Easy -to -build and easy -
to -use. No other generator on
the market offers so many features
at such a great price saving.
