Data and information from Machlett Laboratories, Inc. Machlett started making X-Ray tubes in 1897 in New York City. They moved to Springdale, Connecticut (a suburb of Stamford) in 1934. When Western Electric was required to exit the commercial broadcast transmitter business in 1948, for anti-trust reasons, they transferred their broadcast tube line to Machlett, hence Machlett's types ML-212E, ML-222B, ML-279A, ML-357B, etc. In 1959, Machlett was purchased by Raytheon and run as a separate division. In 1988, the Machlett division was sold to Varian. Later, the Machlett brand name was purchased by Penta Labs.
