    LOL! Yes there is such a vacuum in our atmosphere (same as these glass-less tubes experience). I would buy 'em; after all he did say "they may still work". :#

    Yeah, and you don;t have to worry about those pesky getters either. Those annoying getters just get in the way the electrons. (Oh, wait.)

    The getter is usually barium (edit: barium alloys, I guess).

    Beryllium and beryllium compounds are quite toxic.
    LD50 is about 160 mg/kg.

    Maybe "vaccum tubes" should be "vacuous tubes"?

  • Saw the thread title and thought, "Huh. 'Atmospheric' ? Must be a new tube company !".

    But ... no. :o I'm kind of curious, how does one carefully remove the glass on each tube ?
    Maybe "vaccum tubes" should be "vacuous tubes"?

    REPORTED !

    {What ? Oh, I didn't notice that. Thanks}

    NOT REPORTED !

    1) Improved visibility of light in dark environments.

    2) Easy access for cleaning and maintenance.

    3) Better heat dissipation.

    4) Unneeded glass can be recycled or used for unique Christmas ornaments.

    5) Released vacuum can be collected and used for other science projects.

    Personally, I'd ship the tubes off to Muppet Labs - where cutting edge technology is their daily fare.
