風冷三極管系系金屬陶瓷結構、碳化釷鎢陰極、強迫風冷三極管。 陽極耗散為1kW, 工作頻率為110MHz，陽極輸出功率為3.8kW。主要用作工業高頻振盪器，可與湯姆生產的5867A(TB3-750) 型電子管互換使用。
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。
