Abstract: A cathode structure for electron discharge tubes comprising parallel filament wires extending longitudinally in an axial plane of the tube with all wires carrying input current arranged as a group on one side of the center of the structure and all wires carrying output current arranged as a second group on the other side thereof, filament support rods having peripheral grooves at equally spaced intervals along the length thereof attached at one end to the filament wires and at the other end to respective coil springs, and thin metallic frames surrounding each group of filament support rods in planes perpendicular thereto such that the ends of opposing cantilever arms attached to the frames engage the peripheral grooves of the support rods to restrain lateral movement thereof while permitting longitudinal movement to allow the coil springs to compensate for thermal elongation and contraction of the filament wires.
