Triode 8T25RA

Triode 8T25RA-type electron tubes are metal ceramic triodes, with their anodes cooled by air, and their maximum anode dissipation powers at 15kW; when at a frequency not higher than 40MHz, their output powers may attain to 31kW. They are mainly applied in industrial high-frequency heating equipments for oscillations or in radio equipments for amplifications.
