6BM5: Fertigungsdatum unklar

Können bitte die Röhrenspezialisten nachsehen ob diese Röhre erst 1954 gebaut wurde obwohl sie schon am 30.Jun.1952 in der "Electron Tube Registration List" genannt wird?

Besten Dank und Gruss,

GR

Hallo Georg,

der Eintrag in der "Electron Tube Registration List" stimmt (immer noch). Bemerkenswert ist, dass diese Röhre nur auf dem französischen Markt auftritt, darunter 2 Geräte mit Fertigungsjahr 1953.

Grüße, Jacob
