SPECIAL RATINGS & PERFORMANCE DATA ster-Cycling Life Performance: This test is performed on a sample tot of tudes from each production rune A minimum of 2000 cycles of intermittent Gperation is applied under the following conditions: heater Volts = 7.5 cyeled one minute on and one minute off, neater 135 volts positive with respect to cathode, and af! other cienents connected to ground. At the end of this test, tubes are checked for heateracathode shorts and open cir ITransconductance at Reduced Heater Voltage: With heater volts = 5, plate supply volts = 250, grid no. 4 Connected to cathode at socket, grig-Ne-2 supply voles = 100; and cathode resistor tonne) bypassed = 80. 5-59 ELECTION TUBE DIVSION DATA
