All tubes are tested for emissions and shorts with a Knight 600B tester.  As this is not a complete test (NOTHING is...), I will take any back if you pay shipping - unless I misrepresented it, in which case, I'll take care of postage.  This list will be updated occasionally, but will probably NEVER be completely accurate.  Email and I'll check what I really have.  Priority mail is 3.95 for up to a pound.
