Triode FU-501

Triode FU-501-type electron tubes are glass triodes, with their anodes cooled by air, and their maximum anode dissipation powers at 450kW; when at a frequency not higher than 30MHz, their output powers may attain to 1500kW. They are mainly applied in industrial high-frequency heating equipments for oscillations or in radio equipments for amplifications.
