Abstract
An electrical connective improvement is provided for a multiple-element electron gun assembly in an electron tube. The improvement relates to an isolated electrical conductor extending within the envelope from one of the elements of the electron gun assembly to the closure portion of the tube, whereat the conductor is shaped to project into and be encompassed by the exhaust tubulation wherein a portion of the conductor is sealed. Removal of the exterior portion of the tubulation beyond the seal provides an electrical connection extending exteriorly thereof.
