The Soul of an Old Heathkit

Howard Nurse’s first Heathkit was the DX-40 ham radio transmitter.

Howard Nurse built hundreds of Heathkits. As a kid, he loved to go to sleep reading the catalog — a window into the world of electronics and a wish list of things he wanted to build.

You have to understand the whole experience of a Heathkit,” Nurse said. “It began with the catalog, which became part of my dreams and fantasies.” Once he had placed an order, he would count the days until his Heathkit box arrived at his home in New Jersey. “Finally you’d get the package in the post box, after all this anticipation.”

Electronics weren’t readily accessible in the 1950s. The only place Nurse could see electronic components was at a local TV repair shop, which he hung around. The Heathkit catalog opened a door to the new worlds of hi-fi components, electrical test equipment, ham radios, and television sets. His first build was a ham transmitter, the DX-40.

Nurse recalls the joy of opening up the Heathkit box. “First, you’d see the Heathkit manual, which was the heart of the kit.” Then he’d find the capacitors and resistors in brown envelopes. A transformer came wrapped in spongy paper, a predecessor of bubble wrap. “Before you did anything, you had to go through the errata that came with the kit.” Then he’d inventory the parts and sort them in a muffin tin.

“After all this waiting and preparation, you’d begin to assemble the parts,” he said. “You started by attaching a few components, and then you got to solder, which was really fun.” When you finished and tried it out, often it didn’t work. This, too, was part of the process of understanding electronics and learning to fix problems.

Nurse eventually got an insider’s view of Heathkit. In 1964, his father, David W. Nurse, joined the company as vice president, just as Howard was going off to college. He was promoted to president in 1966 and remained in that position until he retired in 1980.

The Heathkit Company got its start in the 1920s as the Heath Aeroplane Company. Founder Eddie Heath developed do-it-yourself aircraft kits; his most famous was the Heath Parasol, with an overhead wing. Unfortunately, he was killed in 1931 in an airplane accident.

An engineer named Howard Anthony bought the company from Heath’s widow in 1935. After World War II, Anthony bought a large stock of surplus wartime electronic parts, among them 5″ CRTs (the legend is that he ordered a case but a carload arrived). He designed an oscilloscope kit for $39.50 and began to sell it through mail order. It took ten years to go through the original CRT shipment. According to an excerpt from the Heathkit Catalog found on, Anthony’s success was based on “the premise that anyone, regardless of technical knowledge or skills, could assemble a kit himself, and save up to 50% over comparable factory built models. All that would be required were a few simple hand tools and some spare time.”

In 1951, Anthony also died in an airplane crash. The company changed ownership several times, but continued to produce innovative kits, including a color TV set in 1964. Heathkit did $100 million in annual sales in the 70s on a wide variety of kits, including furniture and satellite TV receivers.

“The Heathkit philosophy,” said Nurse, “was that they didn’t invent new products; they looked for products that were already successful in the market,” then turned them into kits for the DIY market.

Nurse believes he may have had a role in persuading Heathkit to undertake its first digital computer. In 1975, the cover of Popular Electronics featured the MITS Altair 8800, which originally sold as a kit that required the user to solder and assemble the components. Noticing that it was selling well, he told his father that there should be a Heathkit computer. In 1977, Heathkit launched the H8 Digital Computer, and it proved to be extremely successful. Based on the Intel 8080, the H8 came with 4K of RAM and a cassette-tape-based operating system. It had a keypad on the front and a nine-digit display. Nurse wrote a radio Teletype software program for the H8 and started his own business selling it.

In the 80s, interest in DIY electronics declined, and the Heathkit Company stopped making kits. The old Heathkits live on as memorabilia exchanged on eBay, and in enthusiast websites and Yahoo! groups.

“I’ll bet that every engineer in this country over the age of 50 grew up building Heathkits,” said Nurse. “Heathkits were special. The best way I can explain it is,” and he paused. “A Heathkit had a soul.”

UPDATE: heathkits are back!

In September 2011 Heathkit resumed selling kits for the DIYer. Look for new home electronics kits — Garage Parking Assistant, Wireless Swimming Pool Monitor — and soon, tube-driven audiophile gear and amateur radio kits.
