Matched Pair General Electric GE 6K6 6K6GT Vacuum Tubes Black Glass North Carolina Press minimum (65%) is 1690)This matched pair of GE 6K6 6K6GT tubes was tested on our Maxi Matcher 2 with 325 volts on the plates and a bias of 36 volts for shorts, gas, plate current and transconductance. There were no shorts or gas. Tube One measured 1570 micromhos, 19. 6 milliamps' plate current. Tube Two measured 1650 20. 2. New nominal is within one standard deviation of 1900. These tubes have copper support rods; rectangular mica spacers; black and silver bottles and 2 04
