Triodes for Zeus displays

Summary:Power considerations lead to the choice of wire cathodes for the supply of current to the channels in a Zeus display panel. Each channel has its own triode, modulated by a separate G 1 grid. Cathodes and other electrodes are in common use. The design of the triode is guided by the need for low modulation voltages, somewhat at the cost of mechanical tolerances and emission stability. The result is an integrated triode section that can supply 200 μA per triode, which is sufficient for a 40″ display, at 15 V modulation voltage. A dynamic control system ensures emission uniformity over all channels.
