Heathkit was the original electronics kit company, and their kits were extremely popular after World War II. Their first popular kit was an oscilloscope, which sold for around $50 (a lot of money at the time, but a bargain compared to available commercial oscilloscopes). The main selling point for Heathkits, was that if the purchaser bought a kit, and built it themselves, they would be more able to troubleshoot and repair issues.
