Here is one very strong gray solid-plate that tests as new (TAN) with no gas, no shorts, lots of getter-flashing and excellent life-test. This tube has three support posts and three 'O' shaped getters, i.e., one top getter, and two side getters. I don't know if this tube is new; but it looks perfect and tests stronger than the average new 6550.322PF3 Gm = 6750 / where 6500 = AVERAGE NEW MEASUREMENT / and 4095 = JAN MIN
