Abstract :
A plane-electrode triode is described which may be operated as a grounded-grid amplifier to obtain 1.5 kw at frequencies up to 700 mc. It operates with 3,000 volts on the plate, is water cooled and has an oxide-coated equipotential cathode. The grid is of an unusual design, made of copper and is nonemitting. The performance at 500 mc is 1.5-kw output, apparent efficiency 55 per cent, power gain 6.5 times.
