Here is a repaired, calibrated, tested and fully working EICO 628 tube tester.  From its hang tag (see pics), it appears to be factory wired and not a kit.  Overall it is in pretty good condition with some waviness in the upper right corner of the faceplate where I straightened a bend (see pics). This tester is shown testing several tubes in the pictures.  (The tubes are for demo only and are not included in this sale.)  One of the pictures shows a 9-pin miniature under test.  This tube is weak and leaky.  The tester properly detects these problems.  The other two tubes are good and test accordingly.  (The voltage regulator tube is good with a reading above 20.) This tester will test most "modern" consumer vacuum tubes post WWII.  It has sockets for testing Audio, Rock 'n Roll, TV, Color TV and Amateur Radio tubes including Compactron horizontal sweep output tubes as sometimes used in RF Linear Amplifiers.  In addition to Octals, Loctals, 7-pin miniatures, 9-pin miniatures, Compactrons and Novars, it can test 5- and 7-pin Nuvistors and 9+1 miniature Decars.  That's a lot of tubes.  The EICO 628 can test antique radio and audio tubes, but requires an adapter for the antique sockets. All the switches and controls work well, the sockets are very good, Lights are bright, and the meter is smooth and repeatable.  The case and handle are solid. Please let me know if you have any questions.
