ABSTRACT:
In a two-digit glass indicator tube the cathode segments with their supply conductors are fixed by enamel to the flat rear walls below a frame of sintered glass against which the front wall bears. Bent parts of conductors and electrodes determine the distance between the front wall and the rear wall. Other parts clamp a mica plate on the supply conductors.
