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.
