Up for sale here is this vintage Triplett 3413 tube tester.  This is in pretty good condition--the case has some rust/corrosion on it, but isn't too bad.  The leather handle is a bit fragile--I would not recommend holding it by the handle.  I replaced the power cord, which was brittle and cracking.  This does work--I put in a tube and the meter moved to indicate that it was good.  This may need a recap/rebuild or at least calibration.  This is sold as working but possibly in need of rebuilding.  It appears to be 100% complete and includes the roll chart as well as a supplemental chart, but there is no instruction manual.  The roll chart has some slack in it and you may have to spin it a bit in one direction or the other in order to pick up the slack, but it will work.  You may need to re-roll the roll chart or something--I'm sure there's a way to get the slack out of it.  The lights do work--the illumination on the roll chart is really nice.  This is a neat vintage tube tester, and could be yours!  Please see my pictures for details.
