RE: Fake Tubes/Bad Seller?

I have quite a few of these of different vintages and with different markings, and all are genuine Amperex 7316's as far as I know. But regardless of the exterior printing or vintage, they are all totally identical internally. If the tubes you bought are similar to the Ebay ad Michael linked, I'd say it's almost certain you got fakes (and especially if you bought them from "old_guy_radiola"). None of the tubes I have are black plates and none have shiny plates (they are all matte gray). I cannot see any crosshatch in the top of the glass in the Ebay tubes that would indicate a genuine Amperex. All my 7316's have a round top getter, and while it's difficult to see in the Ebay photo, it doesn't look like the getter is round in those tubes. And it would be rather strange for the exterior printing to be in nearly flawless condition for tubes of that age. The Amperex screening comes off just by touching it on my tubes, so I'd guess that the printing on those tubes is pretty recent.
