• Examples of Use of Design Ranges
Unless and other specified voltage values are for each gun and are positive with respect to Cathode.

Anode Voltage 22,000 volts Grid No.3 (focussing electrode) 5,720 to 6,600 volts
Grid No.2 voltage when circuit design utilizes Cathode voltage of 160 volt 460 to 820 volts (for visual extinction of focussed spot) Heater Voltage - Under operating condition 6.3 volts rms
Note: For maximum cathode life, it is recommended that the heater supply may be regulated.
