| Description |
After high-gm output penthodes were launched in the UK as early as 1933, this new genre of tubes came to continental Europe in 1935, as the AL3 appeared by Philips, with a round (cylindrical) cathode and a gm of 9 compared to 2,5 mA/V of earlier types as a new standard in Europe which remained until the end.
As in 1936 Telefunken launched the almost identical AL4 with an improved profiled cathode, Philips, Tungsram and other companies then renamed their existing AL3 also into AL4 and continued producing it unchanged. The type AL3 was withdrawn and replaced by the AL4. [J.R. Jan. 5, 2017]
