ABSTRACT:
An electron tube base comprises a cup-like housing and a wafer flange extending radially outwardly from an open end of the housing. The base is mounted over the stem of an electron tube with the stem's exhaust tubulation disposed in the housing in a close fit and the stem's lead-in conductors extending through apertures in the flange. The flange has a dielectric-receiving recess around one of the conductors and the internal surface of the housing wall has a pair of open longitudinal channels along which the dielectric material can be force-flowed into the recess from the opposite end of the housing.
