Just wondering what you folks think of a superior model 82a tube tester?
I repair a few old radios for fun and have been needing a tube tester. One that will be good for a hobbyist. I have also been looking at the B & K models.

I'm 16 and have been at this hobby for around 5 years, and I owned an 82A. They are decent testers, and certainly get the job done for a hobbyist looking to see if a tube is good to use. My main "go-to" tube tester is a Superior model TV-11. I also have a Precision model 10-12, which I will use when I need a more accurate measurement. The TV-11 and the 82A are both good testers!

They aren't high end mutual conductance testers, but for hobbyist work like we do, you don't need one. They are both basic emissions testers, and work very well!

Its a basic tube tester, it will check for shorts (MOST important to check 1st)
You can tell that the 82a tester is basic by the lack of knobs.
Some techs like to check for shorts, maybe basic emissions, then put it in and listen to it.
Even a tube that checks ok may not sound the best.
You can spend from $20 to $2000 on a tester, and both will say if its good/bad (referring to shorts test only)
What do you want to do, match tubes, or just check operational functionality ?
How much you want to spend?
And not all tubes have "gain" to measure like a 12ax7, some tubes are just regulators and rectifiers, no fancy test needed.
Again, a simple shorts test will suffice for all those.
But with that all being said, we all love big fancy testers like the Hickok 539c, and many of us have several, or several dozen !!
good luck buddy.
But I would pass on the 82a and get a Knight 600b, or similiar, Eico 667, B&K 500, not quite a full blown tester, but better than the 82a and prices are <$100.

here's a nice little tester, clean, quick and easy, does shorts and gas test, so you at least know a tube is functional
