Les anciens tubes de la MBLE, sous la marque Ultron
Dès les années 20, les tubes électroniques (lampes) furent produites par la MBLE.
Dans les années 20/30, la MBLE a construit des lampes type américain sous la marque ADZAM, et les tubes européens sous la marque ULTRON.
Si les lampes ADZAM avaient des numéros standards, les tubes ULTRON ont eu une numérotation spécifique.
Voici la table d'équivalences entre les tubes Ultron
avec numérotation spécifique et
ceux d'autres marques (source : catalogue non daté des tubes Ultron,
édité par la M.B.L.E.).
