In 1947 The Heath Company, which was at that time buying and reselling war surplus aircraft and electronics equipment, purchased an equipment lot that contained hundreds of 5BP1 cathode ray tubes. The owner of the company, Howard Anthony, got the idea of using the CRTs as the basis of an oscilloscope kit that could be sold at a very inexpensive price. In the summer of 1947, the company placed an ad in a popular electronics magazine called "Radio News" advertising the oscilloscope kit (model O-1) for sale for $39.50. Orders began comming in immediately. The success encouraged Anthony to create other kits, and in late 1947 he rehired an electronics designer that earlier worked for him designing aircraft radios.

The second kit created was a Vacuum Tube Volt Meter (VTVM) (model VT-1). The third kit was for a Radio Frequency (RF) Signal Generator (model G-1). By mid 1948 there were also kits for a Sine and Square Wave Audio Generator kit (model G-2), a Signal Tracer kit (model T-1) and a Condenser Checker kit (model C-1).
