General Electric UV-210
AC Audio Output/Transmitting Triode
1924

The UV-210 was a replacement for the UV-202 transmitting tube and was also used in applications needing high audio output. In 1924 a number of these tubes were supplied to the Navy. It was also used by both GE and RCA in commercial receiveing equipment. The UV-210 was not advertised and was apparently never sold to the general public. The UV-210 was replaced by the UX-210 that was announced by RCA in late 1925.
