For those of us who like to wax
nostalgic over our early days of building electronics kits, here is a two-page spread from
Heathkit in a 1969 issue of Electronics Word magazine. That year was pretty much
at the beginning of my more serious involvement in electronics, which had spawned a few years
earlier but was really kick-started after getting a "Radio Experimenter" kit for Christmas.
It had parts for an AM radio with a breadboard that used springs as attachment points for
the components. Being "so easy a caveman could do it" (per a certain set
of insurance company commercials), I actually was able to hear a broadcast through
the ear bud from the local AM radio station (WNAV in Annapolis, Maryland). It would be a couple more years - probably
because I had not heard of them until then - before I was able to buy a Heathkit multimeter
kit. The rest, as they, is history.
"Performance-Plus" Kits For Shop And Home ... From the Leader Heathkit
Heathkit IG-18 Solid-State Sine-Square Wave Generator
A precision source of sine or square waves at a low kit price ... that's the new solid-state
IG-18 from Heath. Delivers 5% accuracy thru the wide range of 1 Hz to 100 kHz. The sine wave
section features less than 0.1 % distortion thru the audio range, 8 output voltage ranges
from 0.003 to 10V, switch-selected internal 600 ohm load or external load and metered output
of both voltage & dB. The square wave section has a 50 ns rise time and three output voltage
ranges from 0.1 to 10 V P-P. Both sine & square waves are available simultaneously and
the frequency is switch-selected for constant repeatability and fast operation. Circuit board
construction makes the new IG-18 easy to build ... new Heathkit styling and engineering excellence
make it easy to use. Put the new IG-18 on your bench now. 10 lbs.
Heathkit IM-18 VTVM
The new Heathkit IM-18 continues the features that made the IM-11 famous ... 7 AC and 7
DC voltage ranges that measure from 0-1500 volts full scale ... 7 ohms ranges for measurements
from 0.1 ohm to 1000 megohms ... the convenience of a single probe ... 11 megohm input impedance
... ± I dB 25 Hz to 1 MHz response ... precision 1% resistors ... DC polarity reversing
position on the function switch ... RMS & P-P AC voltage and dB measurement capability
... precision 4 1/2", 200 uA meter for extra sensitivity. In addition, the new IM-18 has 120
V. or 240 V. AC wiring options, new Heathkit styling and a 3-wire line cord for safety. 5
Heathkit IM-13 "Service Bench" VTVM
The Heathkit IM-13 has the same performance specifications as the new IM-18 above, but
it also incorporates other features that put it in a class by itself, such as a large, easy-to-read
6" meter ... extra 1.5 and 5 volt AC ranges for additional accuracy ... convenient gimbal
mounting that allows attachment to your most convenient surface ... "Set and Forget" calibration
- all controls are adjustable from the front panel with a screwdriver ... smooth ten-turn
vernier control of Zero and Ohms adjust for greater accuracy and easier setting ... clean,
open parts layout and a readily accessible "ohms" battery. Assembly is easy, thanks to the
famous Heathkit manual, and operating convenience and versatility are tops. For maximum value
in a general service VTVM, you just can't beat the Heathkit IM-13. 7 lbs.
Heathkit IM-38 Laboratory AC VTVM
For all around general service work, audio design or laboratory analysis, there isn't a
better value than the new Heathkit IM-38 AC VTVM. Here's why - 10 voltage ranges measure from
0.01 to 300 volts RMS full scale ... extended frequency response of 10 Hz to 500 kHz at ±1
dB ... 10 megohm input on all ranges for higher accuracy ... wide -52 to +52 dB range ...
VU-type ballistic meter damping ... very low AC noise ... 120 or 240 VAC wiring options and
new Heathkit styling in sharp beige & brown with an easy-to-grasp, easy-to-read knob.
Heathkit IP-18 1-15 VDC Power Supply
If you work with transistors, this is the power supply for you. All solid-state circuitry
provides 1-15 VDC at up to 500 mA continuous. Features adjustable current limiting, voltage
regulation, floating output for either + or - ground, AC or DC programming, circuit board
construction, and small, compact size. 110 or 220 VAC. 5 lbs.
Heathkit IT-18 In-Circuit Transistor Tester
In-Circuit transistor testers don't have to be expensive, and the IT-18 is proof of that
· ... tests DC Beta 2-1000, in or out-of-circuit ... leakage Icbo and Iceo current 0-5000
uA out-of-circuit ... identifies NPN or PNP devices ... tests diodes in or out-of-circuit
for opens & shorts ... identifies unknown diode leads ... matches PNP & NPN transistors.
The IT-18 is completely portable - runs on just one "D" cell. Easy to use too ... rugged polypropylene
case, attached 3' test leads, big 4 1/2" 200 uA meter, all front panel controls, 10-turn calibrate
Heathkit IM-17 Solid-State Volt-Ohm Meter
Another very popular volt-ohmmeter from Heathkit engineering and it's easy to see why -
all solid-state circuitry ... high impedance FET input, 11 megohms on DC, 1 megohm on AC ...
4 AC voltage ranges ... 4 DC voltage ranges ... 4 ohm ranges · .. 4 1/2" 200 uA meter ...
3 built-in test leads ... DC polarity reversing switch ... zero-adjust & ohms-adjust controls
... continuous 12-position function switch. And that's not all - the IM-17 is battery powered
for complete portability and comes in a rugged polypropylene case with built-in handle. Simple
circuit board assembly. 4 lbs.
Heathkit IG-57 Solid-State Post Marker/Sweep Generator
The new IG-57 plus a 'scope is all you need ... no external sweep generator required. Switch
selection of any of 15 crystal-controlled marker frequencies (you can view up to six different
frequencies on one 'scope trace). Select the sweep range and you are ready to instantly see
the results of any changes you make. Four markers. for setting color bandpass, one for TV
sound, eight at IF frequencies between 39.75 & 47.25 MHz plus picture and sound carrier
markers for channels 4 & 10. Three sweep oscillators produce the 5 most-used ranges ...
