Criteria for evaluation:
reverse grid current, μA not more than 1
slope of the characteristic, mA / V not less than 7.5
Maximum permissible electrical quantities:
Voltage of glow, V 5.7 - 7
Anode voltage, V 300
Anode voltage at a locked lamp, V 470
Anode voltage when the lamp is locked in pulse, V 1000
The grid voltage in the pulse is negative, V 200
Voltage between cathode and heater, V:
with a positive potential of the heater 200
at a negative potential of the heater 200
Cathode current, mA:

in the pulse 200
Power dissipated by the anode of each triode, W 1.8

NOTE:
When operating the lamp, the values of the values that determine the mode should not exceed the specified limits. Failure to do so may result in loss of operability.
