EABC80 / 6AK8 und 6T8: Unterschied Die EABC80 / 6AK8 hat eine bessere Abschirmung zwischen Heizfaden und den anderen Elektroden, besonders zum Steuergitter der Triode, zur Unterdrückung von Brumm. Dazu werden bei der EABC80 die Katoden von F oben H geheizt und die Röhre ist dadurch höher. Ansonsten sind EABC80 und 6T8 gegenseitig austauschbar.
