Does anyone know if this is worth keeping and using or not?

not as good as a proper mutual conductance tester, but still useful for sorting out the dud tubes from the good quickly. you might also be able to test for shorts with the tester.

I have thought about posting pictures of my testers but I don't feel like going through all of them. I have about 10 working and calibrated. I went on a tester purchasing binge a few years ago. .. too much so, but testers are cool.
Necroposting at its finest :)
But while I am here... some of my goodies. Boy do I feel for the people that hand wired these back in the day. You do have to love that wonderful early electronics smell. Fills my whole office!
- B&K 707 black case - calibrated and tested, slightly modded. Soon to be 12ax7 modded. Museum quality of course (besides the mods) Courtesy of BMF right here on head-fi.
- Sencore TC-142. Calibrated and repaired by me. If a tube is leaking - it will find it.
- Precision Apparatus 920. In a slow process of being revived. works partially... well only one side works in dual triode testing. Outstanding condition other than the handle. Will replace when I find the correct one.
Nice - didn't know this thread existed.
I can't compete with the Hickok stuff, but I do have a couple of nice Jacksons:
A fairly typical 648S:
(A very nice Jackson 658A seen on the right.)
My pride and joy is an immaculate B&K 747 (fully restored and calibrated):
