Métal used IRIS as an export brand. Next to each other you see a Métal 6/100 and IRIS type 6/100.


The French base (now called B4) is the oldest European base. But there is another early French 4 pin base, the so called Paris base. As for seize it is about as big as a bigrille base, missing one pin ofcours. Down below you will see a Métal type 6/100 with Paris base, the base itself and the Paris socket compared with a B4 socket.

Y base 

Hi Peter,

As french, I know this base as the Y base. First time I hear the "Paris base" name. Tubes with this base are very rare,
