Introduction:
1. FU-834F and FU-834FA electron tubes are high-power cermet triodes. The direct-heated thorium carbide cathode and anode are cooled by forced air cooling. The maximum power dissipation of the anode is 10kW, and the output power can reach 30kW when the frequency is not higher than 60MHz
2. Mainly used for vibration and amplification in industrial high frequency medium heating equipment. The cathode and filament of FU-834FA electron tube adopt flexible leads, which simplifies installation.
