Triode 833A / 833C

Triode 833A/833C-type electron tubes are glass triodes, with their anodes cooled naturally, and their maximum anode dissipation powers at 300W; when at a frequency not higher than 30MHz, their output powers may attain to 1kW. They are mainly applied in industrial high-frequency heating equipments for oscillations or in radio equipments for amplifications.
