5867A is a direct thermal carbonization thorium-tungsten cathode glass triode anode cooling method is natural cooling,the maximum anode dissipation power is 350KW,the maximum operating frequency is 50MHz,the output power is 1.2KW.the tube is applicable in the field of industrial heating,power amplification or oscillation,also applies to the use of audio and RF power amplifier or modulator.
Note: generally under matched load can be naturally cooled,but the equipment must be well ventilated,if it a non-matched load,high pressure,high-frequency conditions required for forced air cooling,ventilation should be through the outlet from the tube at the bottom of under the previous air.
