    Description

    *** USA Shipping Only!!!  *** No International Shipping!!! ***
    Up for sale is one rare Oak Ridge Products Model 107 Dyn-A-Tube miniature hand held tube tester, circa 1950's, in near mint working condition.  I say "near mint" due to the usual cracking in the external plate cap wire, which is very common in 60 plus year old soft rubber test leads.  Other than that, it appears almost factory fresh with the original case, in excellent condition, and the original attached tube chart, also pristine.  This model was often included in home correspondence electronics courses back in the day.  It will test a variety of 7 pin, 9 pin, Octal and Loctal vacuum tubes.
    Please see the photos for details, including the ones showing an actual test of both sides of a known good 12AU7 tube.
    Thanks for looking and, if you end up the new owner, thanks very much for helping me find a new home for one of my favorite "yesterday's treasures".
