Tube testers are the accepted way to test tubes

Excellet...now I can sell all of my bad tubes on eBay. And to think, I was just going to toss them. Anyone in the market for some SQ's?? Cheap Cheap! Thanks! >

1) Microphonic tubes are not necessarily bad. I have four microphonic DHTs in my line stage and they are the best tubes I've ever used.

2) "preamp tubes" could be taken as a synonym for 'small tubes' - doesn't in itself imply anything about microphonics (position in preamp is critical as has been said)

3) You are suggesting that it's 'fine to sell bad tubes' - it isn't. It's fine to sell tested tubes with the honest test results, which is what most decent ebay sellers do. You get the test reading, plus information about no shorts or gas. I wouldn't ask for or expect anything more and I've bought hundreds of tubes on ebay on that basis.

4) If you have a critical application like phono stage, ask seller in advance. This has been pointed out in numerous posts.

I don't know the exact details of this transaction but if the tubes were tested with honest test results given, and you didn't ask for specific details like noise which would have required listening to them (an unusual service which you'd have to request) then I don't know why you think you are hard done by.
