Of the many projects they worked on, their very first financially successful product, was a precision audio oscillator, the Model HP200A. Their innovation was the use of a small incandescent light bulb (known as a “pilot light”) as a temperature dependent resistor in a critical portion of the circuit, the negative feedback loop which stabilized the amplitude of the output sinusoidal waveform. This allowed them to sell the Model 200A for $89.40 when competitors were selling less stable oscillators for over $200. The Model 200 series of generators continued production until at least 1972 as the 200AB, still tube-based but improved in design through the years.
