G807 - Generator beam tetrode
1 and 5 - Heater (glow) 2 - Second grid 3 - First grid 4 - Cathode Anode - the top cap on the cylinder.

The cathode is indirectly heated oxide. Works in any position. Available in glass design.
Service life - not less than 500 hours.
The base is special. Pins - 5
Interelectrode capacitances, pF:
Entrance - 12.
Day off - 7.
Checkpoint - 0.2.
Rated electrical data of the lamp G807
Heating voltage, V 6.3
Anode voltage, V 600
Voltage on the second grid, V 300
Bias voltage on the first grid, V -20
Filament current, mA 900
Current in the anode circuit at displacement on the first grid minus 20 V, mA 100
Current in the anode circuit at displacement on the first grid minus 29 V, mA 36
Second grid current at bias voltage on the first grid minus 20 V, mA 20
Current in the second grid circuit at a bias voltage on the first grid minus 29 V, mA 4
Slope of characteristic, mA / V 10
Slope of the characteristic at the voltage at the anode and the second grid of 250 V and the bias voltage on the first grid minus 14 V, mA / V 5.9
Output power in generation mode at a frequency of 120 MHz, W 40
Output power at a frequency of 15 MHz with an anode current of no more than 100 mA, a current of the first grid of about 6 mA, a voltage on the second grid of 200 V and a resistance in the circuit of the first grid of 10 kOhm, W 33
Insulation resistance between the cathode and the heater at a voltage between the cathode and the heater 200 V, MOhm 2

In some cases, when using the G807 tetrode in low-frequency power amplifiers, if the voltage at the anode does not exceed 350 V, it can be replaced with a 6P3S tetrode with the replacement of the lamp socket. The replacement results are effective.
