Name: GEC, General Electric Co Ltd., GENALEX; London    (GB)  
Abbreviation: gec
Products: Model types Tube manufacturer
GEC is the most popular name for General Electric Co.Ltd., Magnet House, Kingsway, London WC2.
They used the Trade Names GECOPHONE for their Wireless equipment and GECOVALVE (or Geco) for the valves. Therefore the Brand Name Gecophone is often mistaken for the Company, and widely used.

The Osram division of GEC (at Hammersmith) made lamps from 1895 and from the  1930's made a small range of radio dial/panel lamps.  

The usual abbreviation is G.E.C., but we must not use an isolated character to start with. Search would fail.

In Australia, GEC radio and electrical appliances carried the tradename GENALEX. In the UK in the 1950's, the name GENALEX was used for the series of audio  tubes which were hand made custom tubes for the audio industry. There were several dozen of these tubes made for quite a number of years.  More recently some of these tubes have been made in Russia. 

In 1886 GEC was formed out of General Electric Apparatus Co. which was founded in 1880.
In 1961 GEC merged with Sobell The company celebrated its centenary in 1986. It was sold to Rexcell (France) a few years after this.
