With all the money I "gamble" on audio, maybe I should just buy this and try it.

If you don't live near a dealer who can test tubes for you a tube tester is not a bad investment. That one looks interesting but a bit limited perhaps look into what else is out there?
will this simple unit also test your tubes?

I advise anyone having tube preamp, amp, tuner, phono to get a simple tube tester.

that one looks nice, I want more variety of tube types
