I bought a vacuum tube tester at one of the antique stores near my work. Don't see this kind of equipment very often. I've been looking to get one for a while but Ebay prices are just ridiculous sometimes.
I tried it out on one of my spare tubes. The 6V6 tests good.
I have an old shortwave radio from the 40s it's portable as well. I'll have to post pics of it later on. I do like that tester though it's a unique find.
