Good working tester.  Can test many of the old Western Electric tubes, as well as the typical other 4/5/7 large pins and others. Will not test newer 9/7-pin (12ax7, 50C5, etc).  However, an adapter is available that comes up from time to time. Good tester to supplement your current tester for the old pin tubes. Was calibrated in 2010, per note.  New power cord also installed.  6L6 shows under test, as expected.  I've been using as my backup for tubes, just don't use it enough, need to start thinning out the herd. Good clean condition, case is superb!!
