Re: if a tube's getter has a dark spot in the middle (small area) but...

I've had many tubes, known to be absolutely NOS that had these spots. Especially military tubes, BENDIX, and U.S. NOS smaller signal types, especially Sylvania have them. Some companies actually burned tubes in and tested them. Good ol'American QC...what ever happened to that???
