Description

Tyne page 308ff brings the details of history. Here the main points only:
The first tubes RCA is marketing in 1920 are the detector tube UV200 with argon gas filling and the UV201 Amplifier. Manufacturer was General Electric (GE). Both tubes are operated with a filament current of 1 ampere and at 5 volts. Both have pear-shaped bulbs and are tipped. The base has a mantle of brass with a ceramic insert in thich the pins are imedded. Cunningham is naming his as C-300 and C-301.

In 1922 GE replaces the UV201 with the UV201A, having now a thorium filament.

In 1925 this tube comes with a new base and standardised construction (of 1923) for neutrodyne apparatus and is then called UX201A. Cunningham is naming the tube CX301A.

By having the tube with a shoulder type glass envelope (dome type) in 1932 the designation is changed to 01A. The 01A marks the end of this line of tubes.

The type no UV201 was registered by RCA as a radio trade mark with the US Government on 6th June 1922, being allocated no 155803.

The UV201 from Westinghouse (as a back-up) is different!
