| Beschreibung |
Late in 1924 experiments began at the Westinghouse laboratories on designing a neon gas voltage regulator tube. Work started on development of this tube in March 1925. the tube became available in the following year but it was plagued with difficulties. Research into these problems was transferred to the GE laboratories in March 1927. It was not used in any great extent commercially. The cylinder element was connected to one base filament pin and the other element was connected to the grid pin. With this connection, the battery eliminator cannot be turned on until the tube is inserted in the socket. The tube was originally designed for use with the RCA type 104 amplified speaker.
