    Description

    Cardmatic tested Sylvania National NU Philco engraved base type 26 tubes.
    Theses were tested on a Hickok Cardmatic.  The scale is 0-100. 50 is the demarcation between good and replace.  A tube matching the specs of a new tube would read 82. A measurement of 82 equates to a gm of 1150.
    Here are the readings for these tubes.
    1.  Philco - 61
    2.  NU - 71
    3.  Sylvania - 88
    4.  Sylvania - 71
    Cleaning the tubes is being left to the buyer since often cleaning the tubes also removes labeling.
    Test results are written on the tubes.  These can be easily removed with a moist paper towel.
