German vacuum tubes

1923-1932

The TELEFUNKEN company marking vacuum tubes for use in the receiving equipment, the letters RE, radio tubes for transmitters - the letters RV, and rectifying lamps - letters RG.

Old vacuum tubes from Germany If the designation was the third letter, the lamp with a large number of grids, it was the letter S, and the lamp with indirect heating - the letter N. However, the letter N on the third position was also used for marking rectifying lamps intended for use in power supplies.

The number at the end of the designation indicates the magnitude of the filament voltage, with the exception of lamps with consistent fervor.

Among the direct heating of tubes manufactured by TELEFUNKEN in the second and third decades of the XX century, including during the First World War, the best known lamps marked RE11, RE58, RE78 and RE84 with the filament voltage 4 V.


Later, it has been developed, for example, reinforcing the lamp types RE034 and RE074, terminal transistors RE114, RE134, RE304, RE604 and RE614, tetrode RES094, as well as terminal pentodes RES164, RES174d, RES364, RES374, RES664 and RES964.

Among the lamps from TELEFUNKEN should also be noted rectifiers RGN1504, RGN2004, RGN1304, RGN2005 and RGN1503.

In the early 30s many network receivers were completed, in addition to some of these lamps also triode RF REN904, bass and triodes RENS1284 REN914, respectively HF and LF tetrodes RENS1214 and RENS1204, and HF pentode pentode RENS1224 and terminal RENS1374d.

Combined lamps were presented, for example, tetroddiodami RENS1254 and RENS1854, and multigrid lamp hexode RENS1834, RENS1224 and RENS1234.
