Raytheon

In 1922 three men, Laurence K. Marshall, Vannevar Bush and Charles G. Smith established the American Appliance Company and in 1925 the renamed it to Raytheon Manufacturing Company when they marketed their first Helium filled electronic tube-rectifier to convert AC into DC for household duties in power supplies.

Raytheon means light (Ray) of God (Theos) and the blue light that emerges from their Helium rectifier was similar to the blue supergiant star Zeta Puppis that was examined by Charles Smith when he was working as an astronomer before he established his company.

In the 1930’s Raytheon, after they acquired a tube manufacturer in 1928, they became one of the largest tube manufacturers of the world.
In World War II Raytheon supplied the US forces with magnetron tubes (a British invention) for microwave radar installation and later used the same device in their ‘RadaRange’ microwave ovens the first of their kind.

This was one of the first steps for Raytheon to become a major defense-contractor which they still are up to the current day.

At TubeDirect we’ll try to have some NOS Raytheon tubes in stock like the 12AX7 black plate.
