This is a tested and fully working tube tester.  This unit was repaired, calibrated and tested.  I tested all sockets and switches.  Everything works and this TC-20 is ready to test vacuum tubes.  It will test most modern (post WW2) tubes including rock 'n roll, radio and color TV.  Specifically it will test tubes with the following tube sockets bases: Octal (8 pin large base) Loctal (same as Loktal) 9 pin miniature (Noval) 7 pin miniature 5 pin Nuvistor 12 pin Compactron 9 pin large base (Novar) 10 pin miniature (Decar) The TC-20 tests for shorts and emission.  You can also test for open elements. The sockets are tight, and the meter is smooth and very repeatable.  Overall, this unit is in very good condition.  A prior owner scratched his name and SSN into the case.  Please look at the pictures for more details of overall condition. Tester comes complete with a manual and tube charts.  The tubes shown in the pictures are for demo only and do not come with this sale. This tester will ship by either US Post or UPS depending on total cost of shipping. Please let me know if you have any questions.
“Fully tested & working. Has wear due to age. Prior owner engraved name & SS number in case.”
