风冷三极管系系金属陶瓷结构、碳化钍钨阴极、强迫风冷三极管。 阳极耗散为1kW, 工作频率为110MHz，阳极输出功率为3.8kW。主要用作工业高频振荡器，可与汤姆生产的5867A(TB3-750) 型电子管互换使用。
riode 5867A(TB3-750) 、 5868(TB4-1250)-type electron tubes are high-power metal ceramic triodes, with their anodes cooled by forced air。
Triode5867A(TB3-750) 、 5868(TB4-1250)-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。
