PICKUP CARTRIDGE
The Heathkit MF-1 Pickup Cartridge is absolutely one of the finest
on the market today. It is a low mass moving magnet-type cartridge
that will fit all standard changer and tone arms. Its weight is 10
grams. Impedance is approximately 5,000 ohms. Output at 5 cmper-second recorded velocity is 7 mv at 1 kc ± 1Y, db. Vertical
tracking force is between 2 and 6 grams depending on quality of
tone arm. It will track velocities at up to 30 cm-per-second at maximum of 4Y, grams tracking pressure. The cartridge is nominally flat
from 20 to 20,000 CPS. Vertical compliance is 1 X 10 -6 em/dyne
making it compatible for use on stereo discs. Lateral compliance
is between 2.2 X 10-6 and 3.1 X 10-6 em/dyne depending on the
tracking force applied. Recommended load resistance is 47 k.
Voltage is developed in the coil directly by the magnet (no pole
pieces or transformer action involved), effectively eliminating third
harmonic hysteresis distortion. Shpg. Wt. 1 lb.
KIT
HIGH FIDELITY RECORD CHANGER
Many of you hi-fi enthusiasts who have been looking for a
record changer that will handle your prized records gently,
yet give you the reproduction of which they are capable,
need look no further-the
Heathkit RP-3 provides the automatic convenience of a record changer with the kind of
quality normally expected only from a turntable. Flutter
and wow, a major problem with automatic changers, is
held to less than 0.18% RMS in the RP-3 through unique
design and utter simplicity of the changer mechanism.
One of the many features of the RP-3 is the turntable
pause during the change cycle accomplished by automatically disengaging the turntable drive. This eliminates the
grinding action caused by records dropping on a moving
turntable or disk. The change mechanism disengages
during play, and both turntable drive and change mechanism are disengaged when the changer is shut off, preventing flat spots from developing on the idler wheels
when not in use. Turntable action resumes when the stylus
comes to rest in the next record groove and a smooth start
is assured by a friction clutch on the turntable drive.
Record groove and stylus wear are also practically eliminated through proper weight distribution and low pivot
point friction of the tone arm, minimizing arm resonance
and tracking error. Stylus pressure does not vary more
than 0.9 gram between first and last record. An automatic
speed selector position allows intermixing 33V3 and 45
RPM records regardless of their sequence. Other features
include RC filter across the power switch preventing pop
when turned off, and muting switch to prevent noise on
automatic or manual change cycle. Extremely easy to assemble. You simply mount a few mechanical components
and connect the motor, switches and pickup leads. This
changer is supplied complete with GE-VR-II cartridge with
diamond LP and sapphire 78 stylus, changer base, stylus
pressure gauge and 45 RPM spindle. Dimensions are
13]/," W. x 12" D. Mounting space requires 5" above
changer and 3" below mounting board. Shpg. Wt. 16 Ibs.
Until you've actually put together a Heathkit, you'll never believe how
easy it really is. You don't have to know a thing about electricity,
circuits, or anything else. Every step in assembling a kit is spelled out
for you in plain, everyday language with large picture drawings to
help you along. Even the individual parts are pictured and titled so
there is no chance for confusion.
You'll find Heathkit building a
pleasant family project or a healthy one-man hobby. And when you're
done you will have no end of pleasure-both
from the superior performance of the kit itself and the personal pride and satisfaction of
having done it yourselfl (You'll save a lot of money, too.)

MONAURAL-STEREO PREAMPLIFIER KIT
(TWO CHANNEL MIXER)
This amazing unit allows you to purchase a versatile stereo
preamplifier
NOW-or
buy the high quality
monaural
version and add the second, or stereo, channel later on
if .desired. The SP-1 Monaural Preamplifier
features six
separate inputs with 4 input level controls. Inputs consist
of, "tape-head"
(for play-back direct from transport of deck),
"magnetic
phono"
"Microphone"
and three separate high
level inputs. A level control on the magnetic phono input
allows use of the lowest and highest level output cartridges
and features sensitivity of 2.5 millivolts. Level controls are
also provided on all three high level inputs to allow switching without changing the sound level. An input and compensation selector switch on the front panel selects desired
input and proper equalization.
Selection can be made of
NART8 equalization for the tape head input and RIAA, LP,
or 78 record compensation
for the magnetic phono input.
Separate "level" and "loudness"
controls provide excellent
sound reproduction
regardless of listening level. A scratch
filter with frequency cut-off positions at 5 kc and 7 kc allows
you to play worn records without loss of tone quality. Two
separate 117 V "on-off"
line switches are provided. One
controls the preamplifier
power and three AC receptacles
while the other controls one AC receptacle on the back.
These two switches allow you to control the AC power of
your entire hi-fi system from the preamplifier control center.
An additional AC receptacle is located on the back for the
record changer power. The two "outputs"
provided consist
of a cathode follower output to the power amplifier with
level control, and a tape recorder output. A neon pilot light
on the front panel tells at a glance when preamp is on or
off. The SP-1 is self powered. The built-in power supply
provides for versatile use with any power amplifier.
An ingenious "building-block"
design allows you to convert the
Monaural SI:'-1 to the Stereo Preamplifier (SP-2) by merely pluging-in the other channel (C-SP1). No rewiring is required on the
already
existing
monaural
(A)
channel. The new (8) channel is
identical
with the (A) channel
with the following exceptions: a
function
selector switch is provided instead of another
scratch
filter.
This outstanding
feature
provides twochannel
mixing as well as (A) channel monaural, (8)
channel
monaural,
(A) and (8) channel monaural and
stereo; a remote balance control with 20' of cable allows
balancing the stereo system from listening position. Only
a few minutes are required to plug the (8) channel into
the preamp. The control shafts plug directly through the
(A) channel control knobs allowing the smaller (8) channel
control knobs to operate concentrically
with the (A) channel
knobs. EF86 tubes used in the input stages along with the
individual
hum balance controls on each channel assure
low hum and noise. Construction
is greatly simplified
through the use of two printed circuit boards (one in each
channel) and encapsulated printed circuits. The handsome
vinyl-clad steel cover has leather texture in black with inlaid
gold design. Truly, an unusual value whether you buy the
monaural or stereo model. Measures 4y'" H x 15" Wx8" D.

Titled a "universal"
compact size and variety of uses, the UA-1 provides you with a
remarkable all-around hi-fi amplifier. Except for its lower power
output it has been designed to offer the same high fidelity performance as its big brothers in the Heathkit line, the W-3, W-4,
W-5, W-6 and W-7. Teamed with the WA-P2 Preamplifier, the
UA-1 provides an excellent starting point if you want to keep
initial expenses down and "grow" a larger hi-fi system over a
period of time. In stereo applications, two UA-1 's may be used,
or your present system may be converted to stereo by adding
the UA-1. Some of the other uses include: small wired music
systems for the home; with the electronic crossover; or as a line
amplifier
for unbalanced
lines. These, and many
bridging
more uses, are aided by provision for switching the amplifier
on and off, either on the chassis or in remote locations such
as on the WA-P2. 6BQ5/EL84 push-pull output tubes are used
and harmonic distortion is less than 2% throughout the audio
range (20 to 20,000 CPS) at full 12 watt output. "On-off" switch
located right on the chassis and an octal plug is also provided
to connect preamplifier for remote control operation. Taps for

True high fidelity performance at modest cost make this basic
speaker system a spectacular buy for any hi-fi enthusiast. The
amazing performance of this popular kit is made possible by the
use of high quality speakers in a specially designed enclosure.
The SS-2 is practically
identical to the now discontinued
Heathkit SS-1 Speaker System. The flared tweeter horn rotates
in the SS-2 so that the speaker may be used in either an upright or horizontal position while the horn maintains its proper
horizontal plane. The cabinet is a ducted-port bass-reflex type
enclosure, measuring 11]0" H. x 23# W. X 11y'" D. The total frequency range is from 50 to 12,000 cycles per second. An 8" mid
range woofer covers from 50 to 1600 CPS while a compression
type tweeter with flared horn covers from 1600 to 12,000 CPS.
Both speakers are by Jensen. A variable balance control allows
level adjustment of the high frequency speaker. The handsome
cabinet is constructed of ]0" veneer surface plywood suitable
for light or dark finish. All wood parts are precut and predrilled
for simple, quick assembly. The picture-frame
molding is
supplied with corners squared and glued. An added feature
of the SS-2 is that, although an outstanding performer in its
own right, it may be combined with the SS-1B "range extending" speaker system later to extend the frequency range at
the high and low ends of the audio range. The SS-2 can be
built in just one evening, and will provide many years of listening enjoyment. Shpg. Wt. 26 Ibs.

Attractive brass tip accessory legs convert SS-2 into handsome consolette. 14d legs screw into brackets provided. All
hardware included. Shpg. Wt. 3 Ibs. No. 91-26 $4.95.
This is not a complete speaker system in itself. but is designed to
exfend the range of the SS-2. The SS·1B uses a 15" woofer and a
small super tweeter to supply the very high and very low frequencies
to fill out the response of the basic SS-2 Speaker System at each end
of the audio spectrum. The SS-2 and SS-1B when used together form
an integrated'four speaker system and are designed to combine into
a single piece of attractive furniture. The SS-2 and SS-16 combination provide an overall response of ± 5 db from 35 to 16.000 CPS. The
kit includes circuit for crossover at 600, 1600 and 4000 CPS. Impedance is 16 ohms and power rating is 35 watts. A control is also provided to limit output of super tweeter. The handsome cabinet measures 29" H. x 23" W. x 171'2" D. Constructed of beautiful X" veneer
surface plywood suitable for light or dark finish. Complete step-bystep instructions make this kit easy to build, no woodworking experience required. All parts are precut and pre-drilled for simple assembly. Includes all hardware. Shpg. WI. 80 Ibs.
Increased orders forthe Legato have made more economical quantity
production possible so we are passing this savings on to you by
offering you this magnificent speaker system at a reduced price.
Truly a "queen" among the hi-fi speaker systems, the Legato was
specially designed to meet and surpass the most stringent requirements of high fidelity sound reproduction. Two 15" Altec Lansing
low frequency drivers cover frequencies from 25 to 500 CPS while
a specially designed exponential horn with high frequency driver
covers 500 to 20.000 CPS. A unique crossover network is built in
making electronic crossovers unnecessary. Internal reflections are
absorbed by a splayed back panel and a 3" fiberglass lining. The
Legato emphasizes simplicity of line and form to blend with modern
or traditional
furnishings.

KIT
DX-100-B
The many advantages of single sideband transmission will be of interest to hams now operating
strictly AM or CWo SSB requires less spectrum space, interference and fading are reduced, and
signal strength is increased without greater power output. Designed as a compatible plug·in adapter
for the TX·1 it can also be used with transmitters similar to the DX-100 or DX-100-B by making a few
simple circuit modifications while still retaining the normal AM and CW functions. This modification
will also be available soon in kit form. Extremely simple to operate and tune, the adapter employs
the phasing method for generating a single sideband signal, thus allowing operation entirely on
fundamental frequencies. The critical audio phase shift network is supplied completely preassembled
and wired in a sealed plug·in unit. Features include single·knob bandswitching for operation on 80,
40,20,15 and 10 meters, and an easy-to· read panel meter that indicates relative power output to aid
in tuning. The RF output stage utilizes and EL84/6B05 tube for extremely linear operation. Subchassis type assembly is used for easy construction with high quality components used throughout.
Other features include built·in electronic voice control with anti-trip circuit which allows duplex
operation and prevents receiver output from turning on the transmitter
during listening period.
Panel controls include a 5-position bandswitch, two carrier null controls, balanced modulator and
output tuning controls, and a 3·position sideband selector switch for upper, lower or double sideband.
All sideband modes may be used with or without carrier insertion. Also located on the panel are a
function switch for manual, standby, or voice control operation, audio gain control, and microphone
input. Power for operating the adapter is obtained from the transmitter or from a separate power
supply. Power output is approximately 10 watts PEP (peak envelope power). Less than 3 watts RF
excitation from the transmitter is reauired for the adapter to provide a SSB signal which is then fed
to the transmitter final for amplification.
Unwanted sideband suppression is in excess of 30 db and
carrier suppression is in excess of 40 db. Cabinet measures 10" H. x 6Y." W. x 13" D. A very worthwhile addition to your ham shack to enable you to experience the advantages of SSB operation and

PORT ABLE
Enjoy the safety and convenience of a two-band radio direction
finder that is economical to buy, easy to build and costs only
pennies to operate. The DF-2 is a self-contained,
self powered,
six transistor superheterodyne
radio direction finder. It receives
aeronautical
and marine beacons as well as standard band
broadcasts with startlingly clear tone reproduction
over a long
range. Coyering the beacon band from 200 to 400 kc and broadcast band from 540 to 1620 kc the DF-2 is designed to take
directional "fixes" on both aircraft and marine beacons as well
as standard broadcast stations, while providing the entertainment of a high quality transistor portable radio. You are able
to receive aircraft weather reports every 30 minutes and constant Coast Guard beacons on the 200-400 kc band. A "sensitivity" knob, or RF gain, controls the overall gain of the receiver
which is indicated on the "null" meter. The "bearing"
control
knob on the front panel rotates the ferrite-loop antenna. Other
controls
are: "volume",
vernier
"tuning",
"bandswitch",
"on-off" switch and a dial light for night operation. To extend
battery life, dial light switch must be held down for operation as
the bulb requires many times more power than entire .transistor circuit of the DF-2. Power is supplied by six standard
flashlight batteries which will last up to one year under normal
operation.

For mechanics, tune-up men and auto hobbyists, here is the
ideal tool for analyzing ignition systems. This remarkable instrument traces the dynamic action of voltage in ignition
systems on a fluorescent cathode-ray-tube
screen showing the
condition of the coil, condenser, points, plugs, and ignition
wiring. The analyzer will show the existence of such conditions
as inequality of spark intensity, a poor spark plug, defective
wiring-and
will even identify the offending plug or wire. It will
also detect breaker-point
bounce, an open condenser, or will
allow the setting of dwell-time percentage for the points. These
are a few of the most obvious applications.
More subtle wave

wiil show other ignition system performance
factors, as experience is gained by the operator. The 1A-1 is
simple to use, with a minimum of controls - yet is completely
flexible for all types of internal combustion
engines where
breaker-points
are accessible. Two test leads are supplied,
each ten feet long, which will enable you to reach either the
breaker points or the spark plug wires. Use it on automobiles,
boats, aircraft engines, etc. An important feature of this instrument is its ability to check the dynamic performance of the
ignition with the engine in operation (400 to 5,000 RPM). It will
show the complete engine cycle, or just one cylinder. The
1A-1 is especially helpful in locating stubborn defects which
may show up only when the vehicle is in motion and under
load, if a vibrator-type
converter is used to supply 115 VAC
power for the analyzer. This easy-to-build instrument will help
you make faster more efficient engine tune-ups or repairs and
will pay for itself many times over. Measures 11" H x 5]/," W

LABORATORY
STANDARDS
New helpful
additions
for the electronic
laboratory
are the Heathkit
Lab
Standards.
These units are designed for calibrating,
or'checking
calibration
of various laboratory
instruments,
such as ohmmeters,
capacity meters, impedance bridges, and other measurement
equipment.
They are also handy in
substitution
tests to determine
unknowns in circuits wh ere precision components are necessary.
The lab standards
are comprised
of four separate
units, two resistive and two capacitive, each containing seven highly accurate
precision standards. Banana-pin connectors with the standard %." spacing
are used to enable the units to be plugged directly
into most laboratory
instruments, keeping stray capacity and lead resistance to an absolute minimum. Each unit is constructed
from ten pieces of polystyrene
(eight sides
and two ends) which form an octagonal
cylinder.
A pair of banana pins are
located on seven of the eight sides. Each pair allows direct connection
of a
precision component between th em, yielding seven standards from each unit.
Values are given above. Shpg. Wt. 2 Ibs.
A valuable addition to any modern service shop. This high gain
signal tracer is ideal for tracing RF. IF and audio signals in AM
or FM receivers of either tube or transistor types. The all-new
T -4 employs the latest circuit design and modern tubes to assure dependability
and long life. This compact instrument
contains a unique "noise locator"
circuit that permits the
technician
to locate noisy and intermittent
components
in
various circuits. The RF and audio inputs are combined in one
handy probe. A switch mounted on the probe permits fast,
easy selection of either RF or audio. Signal strength is indicated
both aurally and visually by a 3)1," PM speaker and an electron
beam "eye" tube. This convenient
kit doubles as a utility
amplifier
when servicing
record changers,
tuners,
microphones, musical instrument
pickups, etc. A front panel slide
switch disconnects
the speaker from the output transformer
allowing the T-4 to be used as a test speaker. This is particularly
useful when checking radio or TV chassis where speakers have
been left in the cabinet. The output transformer
may also be
used for a substitute
transformer
if desired. A detailed instruction manual containing
concise step-by-step instructions
along with large pictorial diagrams makes assembly simple
and provides you with useful information on the various applications of the kit. A real "work horse", you can use the T-4 for
years and still discover new applications
from time to time.
Its economical price and outstanding
versatility make this unusual Heathkit a truly worthwhile investment. Measures 7%" H.
x 4%" W. x 4Ys" D. Shpg. Wt. 5lbs.
Time proven for dependability,
accuracy and overall quality
the V-7 A stands in a class by itself. A large 4)1,- panel meter
is used for indication,
with clear, sharp calibrations
for all
ranges. Front panel controls consist of a rotary function switch
and a rotary range selector switch, zero-adjust and ohms-adjust
controls. Precision 1 % resistors are used in the voltage divider
circuit and an etched circuit board is employed for most of the
circuitry. This makes the kit much easier to build, and eliminates the possibility of wiring errors. This multi-function
VTVM
will measure AC voltage (RMS), AC voltage (peak-to-peak), DC
voltage and resistance. There are seven AC (RMS) and DC
voltage ranges of 1.5, 5, 15, 50,150,500
and 1500. In addition
there are seven peak-to-peak AC ranges of 0-4,14,40,140,400,
1400 and 4000. Seven ohmmeter ranges provide multiplying
factors of X 1, X 10, X 100, X 1,000, X 10k, X 100k, and X 1 megohm.
Measures .1 ohm to 1,000 megohms. A zero-center scale db
range is also provided. Battery and test leads also included with
kit. The V-7A is valuable for a multitude of uses. Use it to
measure all operating voltages and potentials such as b+ and
AC-DC, or straight AC power supplies, filament voltage, bias
voltage, AVC voltage, line voltage, etc. Ideal for measurements
in all types of AM, FM and TV circuits. To check discriminator
or detector operation-AVC
or AGC performance-use
the
ohmmeter to measure circuit continuity, circuil resistances, to
test individual
components
with resistance
measurements,
or to trace out circuit wiring through cables or chassis openings. Perfect for laboratory or service shop. Measures 7%" H.
