T-431A-type electron tubes are glass triodes, with their anodes cooled by water, and their maximum anode dissipation powers at 20kW; when at a frequency not higher than 25MHz, their output powers may attain to 30kW. They are mainly applied in industrial high-frequency heating equipments for oscillations or in radio equipments for amplifications.
