A fascinating detailed look inside the labs of ENGLISH ELECTRIC VALVE Company's manufacturing processes provides a fascinating look into the challenges encountered and the techniques used in vacuum tube creation.
The English Electric Valve Company, or EEV, (now part of Teledyne) began in the early 1940s as a part of the Marconi group, manufacturing magnetron vacuum tubes for Radar systems.
EEV was originally registered in 1947 as the “Phoenix Dynamo Company,” but immediately changed its name to English Electric Valve Company.
By 1959, EEV was the largest hitech manufacturing company in the UK. Historically, it is known for the manufacture of electronic components and subsystems for aerospace and defense, healthcare, and commercial and industrial sectors.
This documentary (1968) describes how various vacuum tube devices were created and used.
In March 2017, the EEV company (then known as “E2v Technologies”) was acquired by Teledyne and became part of Teledyne e2v.
