[Milsurplus] tv-7 tube tester

OK.  Like the MX-949/U for the I-177.  The later revisions for the I-177 
tube settings booklet have a section in the rear covering the MS-949.  As the 
extender you have is built into the lid, I would have thought the same would 
be true of your settings booklet.  Unless the extender was added later and 
the booklet didn't get updated.
