| 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.
Later RCA replaces the UV200 with the UX200.
In May 1926 RCA announces the UX200A as a new detector tube, replacing the UX200. The UX200A contains caesium vapor isntead of argon gas of the UV200 and UX200 to get a much more stable operation and increase of sensitivity. The UX200A has a thoriated filament (EE).
