There's no fooling around at the Tube Museum with meaningless claims like "tests strong!" WITHOUT SUBSTANTIATING TEST MEASUREMENTS, or some arbitrary number like "the tube test 82 with a minimum of 75" and no maximum stated! Wide gaps in mA and mA/V is not matched no matter how hard other sellers scream otherwise! Avoid those sellers! They don't show you the H-to-K (heater to cathode) leaks because they can't test for them, or hide the real facts from you! TubeMuseum tested tubes always give you the test results in clear understandable FACTORY-DATA so you can compare with the real factory data sheets in mA and mA/V, just like the original factory data sheet specifications!
