Tube Tester Option

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

This tester does not test octal tubes, only 9 pin tubes.

That is cute, I want one... and some tubes to test!

@gndrbob,  I wouldn't think Atmasphere would have tried this product as it's clearly for hobbyist use.  I would think he has a legitimate Hickok or something commercial and substantial.  

I just need something to test my 9 pin preamp tubes.  I have a ton of 12au7 variants that I want to sell as I no longer need them.  I'd like to be able to make an accurate representation about their condition.  And yes, I realize that absent something like TubeZilla at Upscale, nothing is guaranteed accurate and calibrated.
