Triode 7T85RB

Triode 7T85RB-type electron tubes are high-power metal ceramic triodes, with their anodes cooled by forced air, and their maximum anode dissipation powers at 2.5kW; when at a frequency not higher than 110MHz, their output powers may attain to 5.1kW. They are mainly applied in industrial high-frequency heating equipments for oscillations or in radio equipments for amplifications.
