Matched Pair Tung-Sol 6K6 6K6GT Vacuum Tubes Black Glass NOS-Testing Sequencer An 8 out of 10This matched pair of Tung Sol black glass 6K6GT tubes was tested on our Maxi Matcher tube tester with 325 volts on the plates and a bias of 36 volts. Tube One drew 21. 3 milliamps' plate current while Tube Two drew 23. Transconductance was 1890 for Tube One and 2000 for Tube Two where 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 THOUSANDS OF VACUUM
