WELCOME TO THE WORLD OF HEATHKIT 1969

It is a pleasure to send you this new 1969 Heathkit catalog. It
contains the complete line of Heathkit equipment

stereo/hi-fi, marine, amateur radio, educational, and test
equipment, as well as those of more general intcrcst such as
color television, electronic organs, guitar amplifiers, portable
TV's, radios, phonographs, shortwave, citizens band 2-way
radio, model radio control, and home protection systems.

Since 1947 we have been supplying kits to people who have a wide
range of electronic experience, from novices who have never held
a soldering iron in their hand to expert design engineers. The
significant point is that we are confident that you, regardless
of your experience, can successfully build a kit at home easily,
quickly, with a minimum of effort and a maximum of savings and
enjoyment.

The substantial savings..,up to 50%...is only one of the reasons
why people build kits. Kit building can be a hobby in itself
that adds pleasure to your basic leisure hours interest whether
it be watching TV, listening to shortwave or good music. And,

if you so desire, while building the kit you can learn the
fundamentals of electronics or become familiar with the theory
of such complex products as color television, just by reading
the theory part of the manual.

If you would like additional technical information on any
product, write for a schematic-specification sheet. For more
general information on the hobby of kit-building, write for a
copy of the "Kit-builder's Guide " They are yours for the
asking. And if you have other questions or need guidance in
which kit to choose, our staff of Technical Consultants is at
your service,
~ Sincerely,

DESIGNED FOR THOSE WITH LIMITED SPACE, LIMITED BUDGETS
AND A DESIRE FOR THE FINEST IN A HOME MUSIC SYSTEM.
The AD-27 fits these requirements perfectly. First, its mini-sized. Mczlsurcs
only 217/8W.x14-11/16 D.x77/u" H. Fits just about anywhereeon a
bookcase shelf, on a desk top, And its classic ebony and walnut styling let
it blend with any room decor. Mini»priced too ewont knock your budget into
next year.

WHAT REALLY COUNTS IS THE PERFORMANCE THE AD-27 DE-
LIVERS. Underneath the beautiful exierior of the AD-27 Stereo Compact
is a really performance-plus package. A comparable system Could easily
cost twice as much and still not have all the features of the AD727. Features
like an amplifier that delivers an honest 15 wmls of music power per chan-
nel with a response curve that is virtually fllll from 12 Hz to 60 kHz. An
astounding 45 dB channel separation . . . harmonic distortion thats less than
1% and IM distortion less than 0.5%eboth measured at full output! All
solid state circuitry for heat-free, ll'OUblcrfrcc performance, rugged reliability
and easier construction. Advanced lransformcrless output circuitry that pro:
vides lower phase shift and distortion, and an added feature: proloclion
against severe transistor damage from shorted output leads-another indica-
tion of the extra value Heath engineers have designed into Lhc AD-27 Stereo
Compact.

COOL, CRISP SOLID-STATE SOUND. That's what you get from this one.
The 3] transistor, IO diode circuit is ready lo go the insulin you {lick the
rocker-type power switch. Select the FM Stereo mode and tune effortlessly
across the dial, thanks to the inertia flywheel tuning. The FM Tuner may
be small in size, but it ompcrforms some of the best around, Youll hear
stations you didnt know were on the air, and marvel at the clarity and sepa:
ration of the sound. The adjusmblc phase control insures proper phasing at
all limes-no more poor stereo separation. And the Automatic Frequency
Control puts an end to drift Wonder if that program is in stereo? No more
guessworkthe stereo indicator lights up automatically every time you tune
in a stereo broadcast. Filtered tape outputs provide beat»frce taping loo, And
lhe electronically filtered power supply provides reliable, low noise, ripple
free power to the tuner and amplificr.

THE BSR MCDONALD 500 TURNTABLE HAS FEATURES FOUND
ONLY IN MORE EXPENSIVE UNITS . r . Like a low mass lubular alumi-
num [one llrm that's counterbalanced both Vertically and horizontally for
optimum tracking . . . a continuously variable dynamic untieskale control
that neutralizes \he inward skaliug force and eliminates the distortion caused
by unequal sidewall pressure on the stylus. A cueing and pause control that
lets you select the exact band on the record without fear of cartridge or
record damage. The full-size turntable platter giv s ideal record support and
the scienli cally designed spring suspension minimizes the external shock
susccplibilily that is common to turntables with counterbalanced arms. And
the Shure magnetic cartridge has n .0007 diamond stylus zlnd 20 to 20000
Hz response. Automatic system power (007mm the receiver to off", load
the records and start [he lurnmblcelhc amplifier automatically turns on".
And when the last record is finished, the system shuts itself off. Just one more
example of [he performance-plus" engineering that goes into this Hezltllkit
Stereo Compact,

JUST SELECT THE SPEAKERS AND YOU HAVE A BOX SEAT FOR
THE CONCERTiHIGIIT IN YOUR LIVING ROOM. Many stelco com»
pacts don't provide the buyer with Ilic power and output impedance: neces
sary to fulfill individual tastes and room requirements in speakers. But with
tho AD727 you choosc the speakcheto fit your needsHo fit your budget.
The speakcr outputs will accommodate speakers with an impedance from 4
lo 16 ohms, and power output is sufficient to drive even low efficiency
speakeISebul the final choice is up to you.

EASY TO ASSEMBLE. Most of 1116 components mount on three circuit
boards, and two cable assemblies simplify wiring. Much of the tedious
point-lo»point wiring of comrols and components has been eliminated by
mounting them right on the circuits boards. The from end is pro-assembled
and pic-aligned and all the tuning coils zlre pro-set, requiring only a touchrup

AN ESSENTIAL INSTRUMENT FOR RADIO 8: TV SERVICING.
Saves valuable time by eliminating doubt and guesswork as to tube
quality before further circuit investigations are made. Tubes are
quickly tested for quality on the basis of total emission, for shorts,
leakage, open elements, and filament continuity. ,A fast, positive
evaluation of tube quality. The relative quality is read on a multi-
colored bad-I-good" meter scale and a neon bulb indicator shows
filament continuity and leakage or shorts between elements.
FLEXIBLE OVERALL OPERATION. A Wide range of filament
voltages is available through the frontepanel control switch. Cathode
current is adjustable Meter sensitivity is variable for adjustment to
individual tube characteristics. And individual switches matrix the
tube base contacts. Thirteen 3~position lever switches allow each tube
element to be checked independently for open or shorted conditions.
These are features that protect your IT-l7 against obsolescence , . .
simplify the addition of new tube types to the chart tables. (See note
below for replacement roll charts.)

SPECIAL ROLL CHART MECHANISM. The free»rolling chart
mechanism featured in the IT-17 is spring-loaded to keep the chart
taut as it is examined throughout its entire length. Chart and meter
are both illuminated for easy reading of all tube test data.

EASY TO BUILD. Neat, professional wiring and simplified assembly
is assured with the color-coded wiring harness and casy-to-follow in-
structions supplied. Order your Heathkit lT-17 now for dependable
test facilities at low cost.

switching facilities accommodate virtually all tube types. Sure protec-
tion against obsolescence. The TT-lA provides quick and accurate tests
of mutual conductance (Gm) from 0 to 3,000 micromhos, with rnul»
tipliers to extend this range to 24,000 micromhos. In addition there
is an ultra-sensitive grid current test, a life test, hybrid tube test, a
directereading ohmmeter leakage test, and more. A disconnect switch
removes all voltages from the selector switches to protect both tubes
and tester against possible damage during setup. Cathode buss," plate
buss, and grid buss," switches allow testing of both sections of a
twin triode individually; with only one group of selector switch settings
for extra operating convenience.

SPECIAL FEATURES T0 ASSURE YOU YEARS OF SERVICE.
