A tube tester is most useful in an auxillary, confirmatory role. Or for a 'go/no-go' weeding of large batches of tubes.

Amen. I use my tester (a cheap Sencore "Mighty Mite") once at the beginning of each project, to quickly check the existing tubes and weed out bad ones. After that, it goes back onto the shelf until the next project.

I own other testers (including a Precision 10-12), but they are collectibles, not workhorses.
