Standard Instrument Corp. model 85 tube tester. No longer working on old radios so, letting go of my test equipment. This unit works well and looks very good. Tests 7-pin miniature, 8-pin octal and locktal, 9-pin miniature and nuvistor tubes. Has pin straightening sockets for 7 & 9-pin miniature tubes. Complete with good settings chart for hundreds of tube types. Very portable, not big and bulky like other testers so easily stored away when not in use.
