807QE06/40807 Indirectly heated H.F. beam power tetrode, giving 25 watts up to 30 MHz and 12 watts at 125 MHz. A variation of type 6L6 originally designed as a Class C transmitter tube. Later used in pairs as push-pull outputs for high-wattage Class AB2 audio amplifiers. Also used as a horizontal output tube in early television receivers. One of the first commercial tubes that used the top cap to connect the plate (instead of the control grid) to the circuit.
