Die Röhre wurde von diversen Herstellern gefertigt/vertrieben. Ich besitze Exemplare von CBS, Cetron Electron Corporation, Electrons Inc., Continental Electric Co., Raytheon, United und Westinghouse. In wie weit alle genannten Firmen auch selbst gefertigt haben, ist mir z.Zt. nicht bekannt.

Schönen Gruß

1. Nachrag: Die Röhre wurde auch unter der Bezeichnung "EL 1C" hergestellt (Electrons Inc.).
