I have a tube tester somewhere in the back of my closet. mostly use it for checking small receiving tubes. large power amplifiers and final amp tubes are easy enough to test by just looking at how they perform in the transmitter.

I keep my 2 feet on the ground, and my head in the twilight zone.
I don't have a tube tester. But, I do have a Sencore CRT tube rejuvenator, which is good for getting extra life out of an old oscilloscope, spectrum analyzer or network analyzer CRT. I'm not exactly sure where it is, though.
