Description

Beam-power-tetrode, launched spring 1936 by RCA. Predecessors: none / Successors: none, still in production. 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. First it appeared as metal tube, then in several glass versions, e.g. as 6L6GC with 35 watts dissipation.

Michel Deluz 30.Mar.11	1 6L6 (6L6) La limite pour ce tube en P.P. classe AB1 de 400v anodiques et 300v écran n'est pas donnée par tous les constructeurs ; nous ne connaissons que RCA et STC qui la mentionnent. Ce sont semble-t-il les seuls constructeurs qui font la différence entre les limites pour la classe A et celles pour la classe AB qui sollicite un peu moins le tube.
