need to purchase a calibrated , small signal tube tester-why so difficult?!

Thanks @tomcy6 … very helpful.

Great tip on the noise test too..

I did ask them about emissions. Disclaimer : Although I have an electronics degree etc…I know only the very basic things about tubes. But when he explained it…. It was basically that there are different ways to skin a cat….and that you could still confidently measure, manage and detect good vs bad. without?  But I do not want to put words in anyone’s mouth but my own.

But that’s a great question!!,

************

For anyone inclined : In Plain language, what is “Emission Testing “? Why do we need it?

Notice— I’m not looking to start a. “Do cables matter”-like SH#$STORM …so if you have an 🪓 to grind…please take it elsewhere.

I may start a separate thread…. Emission’s testing. What’s it good for? 🎶
(Never mind, I thought it was funny 😆)

Use Case: for an old audio guy who just wants to manage his small signal tubes.

Bump….

any last thoughts….I’m likely pullong the trigger on the mini2 when I put together the funds.

if I do purchase one, I’ll report back. No…I actually will😉

The biggest problem exists with emissions only testers. They really kind of suck, can damage small signal tubes and can have a very spastic leakage test. Transconductance is a better way to test a tube and much more accurately duplicates the demands of a circuit. Now if you can find a tester that does both transconductance and emissions this is a plus but not as much as some would think.  I have a Maxi-Matcher power tube tester and it is O.K. I have had consistently great results with my vintage Triplett and Hickok testers. Hagerman Audio Labs used to make tube testers, I would tend to go this route if these 2 choices are still available. Hagerman designs audio equipment that uses tubes and I think he might understand the art as well as the science.

Space tech lab has several tube testers starting at under $900
