Here is one New in the original box Channel Master 6K6GT Tube.This tube has the grey plate and bottom getter ring and was made in Japan . I tested the tube on my Hickok 600 mutual Conductance tube tester and it reads new at 2300 micromhos where 1600 micromhos is the average reading of new 6K6GT  tubes given on the roll chart.It has no shorts or gas... Your tube tester readings may be different than my tester, but this tube tests new.  USPS 1st class shipping with tracking is $4. USPS 1st Class International Shipping is $15.
