| Description |
Power output tube; launched mid 1936 by Philips
as pentode, late 1937 by Telefunken as
tetrode. By demand of more output power new output
tubes appeared in 1936 with plate dissipation
increased from 9 to 18 watts. In Europe it were
the pentodes AL5 (4Vf) and EL5 (6.3Vf), in the
USA it was the worlds first and most famous beam-
power-tetrode, the 6L6. Since late 1937
Telefunken also made the AL5 as beam-power-
tetrode.
