Detailed Product Description
FD-911S-type electron tubes are glass triodes, with their anodes cooled by water, and their maximum anode dissipation powers at 80kW; when at a frequency not higher than 26MHz, their output powers may attain to 100kW. They are mainly applied in industrial high-frequency heating equipments for oscillations or in radio equipments for amplifications.
