Details:

It has the signal tracer and decade resistor capacitor bridges. Offered: one military tube tester an/usm-3 tv-4 and set. It works though if you carefully follow the instructions. I will say that the tube tester set up is about most un intuitive thing have ever seen.

This is a Weston made tester and emission quality only. This one is missing all the tools from lid. I tested one 6l6 and 12ax7 you can see the results. No oops manual.
