Matched Pair General Electric GE 6K6 6K6GT Black Plate Vacuum Tubes December 28 2022 4 milliamps' plate currentThis 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 2000 micromhos, 24. 2 milliamps' plate current. Tube Two measured 2160 26. 6. New nominal is within one standard deviation of 1900. As I write, I am playing them in my Mini Mite 2013 and they sound great. WE HAVE SCORES OF
