Hallo zusammen, ich besitze aus einem Mil. Gerät einige Röhren mit der Bezeichnung KF3U. Was hat der Buchstabe U für eine Bedeutung? Im Röhrenmuseum ist diese Röhrenbezeichnung noch nicht vorhanden. Vielleicht kennt jemand diese Röhre. PS: Das Gerät wird nächstens angelegt. Mit freundlichen Grüssen. A.Küffer
