Sencore TC28 Mighty Mite VII Tube Tester
                                                           - Calibrated - 
This TC28 looks like new inside and out and functions the same. I have and use a TC28 and was tempted to keep this one since this is essentially new with no metal tarnish in the places you see on every other TC28. Even the paint looks new. Really nice looking and functioning TC28. 
 
All the tube sockets look unused and are tight and tested the tubes with no issues. 
I will install a new nine pin noval socket on socket 3 at no charge if requested before shipping if you message me you want it.
Includes the Sencore service manual, and a DVD with more. The Sencore Mighty Mite series of tube testers are the best for finding shorts or leakage in a tube, as well as the life test. 
 
I was testing the tubes I put up for sale on my own Sencore TC28 before testing them on a Hickok for micromhos values, but stopped because it was too time consuming. 
Testing on a TC162/TC28 has convinced me to start doing that again since a 5Y3GT (rectifier) tested almost NOS on a Hickok, and when I tested this same 5Y3 on this and many other Sencore TC162/TC28s, it became salient the tube was weak and out of life. 
 
Everything works, shorts, grid leakage, emissions, and life test as well as the transistor test function.
 
I also prefer testing sweep tubes and rectifiers on a Sencore since emissions is what you are testing and more likely to weed out a short, leakage, or a weak tube.
 
Easy setup and all solid state. 
 
This Sencore does not test the older style tubes so please know what tubes this can test before purchasing. 
 
The TC28 was calibrated per the calibration instructions included in the Service manual and on the DVD that is included .
 
Included is a DVD which includes the manual for this TC28, tube data, schematic, calibration; which needs a jig made in an octal socket, or you can buy the jig already made, and other manuals and tube data for similar Sencore tube testers including the TC162 and MU150.
 
This is a bigger beefier tube tester that will remain supported when removed from the case, has a nice big easy to read meter, as compared to the very small TC162 tube tester which is the same tester, but the TC28 has the additional transistor test capabilities.  Also, the TC162 does not have the ability to be used outside the case as the TC28. 
 
The Sencore TC28 is the best tube tester Sencore made.
 
The calibration test adapter and calibration tubes that may be seen in some of the pictures are not included.

Will be packed in a 16X14X10" box weighing 16 pounds.
