polarisation 6C8)

 La courbe de distorsion du 6C8 montre qu'il est linéaire jusqu'à environ -5v de polarisation si on le charge anodiquement avec 100kΩ. Contrairement à ce qui est proposé par RCA (-4,5v), il vaut mieux donc le faire travailler avec -2,5 à 3v de polarisation si l'on désire rester fidèle, ce qui limite évidemment son cursus.
