Triode 7T69RB

Triode 7T69RB-type electron tubes are high-power metal ceramic triodes, with their anodes cooled by forced air, and with a maximum anode dissipation power at 4.5kW; when at a frequency not higher than 110MHz, their output powers may attain to 9.1kW. They are mainly applied in industrial high-frequency heating equipments for oscillations or in radio equipments for amplifications.
