Hallo,

ich habe eine Philips "Evette L3X80T/90" in meiner Sammlung und in dieser wurden OC71.1 in der Vor- und Treiberstufe eingebaut.
Diese OC71.1 haben über den üblichen Glaskörper ein Metallgehäuse, ähnlich dem OC72. habe ich so noch nicht gesehen:

Der Isolierschlauch hält ihn im Normalfall am Chassis fest.
                                                 

Vor- und Treiberstufe des L3X80T/90

Freundliche Grüße,

K.- Heinz Entrich
