I've been drooling after tube testers. It would be nice if it was simple to use. I think my main targets would be 6SN7 and maybe in future 300B. Use case would be tube matching for audiophile use, ie. accuracy and features according to that.

In wikipedia under modern testers it says:

The most modern testers perform a multitude of the below tests and are fully automated. Examples of modern testers include the Amplitrex AT1000, the Space-Tech Lab AudioTubeTester, the Maxi pre-amp tester and the maxi-matcher (power tubes only) by maxi test and the new, and somewhat more primitive, DIVO VT1000 by Orange Amplification. While the AT1000, AudioTubeTester and the Maxi-test brand testers offer precise measurements of transconductance/Gm and emissions/iP at full or near full voltages, the Orange tester offers a very simple numerical quality scale. The AudioTubeTester has a unique feature of quick tube matching +/-percentage display.

As DIVO looks like it's not accurate enough for this use case, the shortlist that I would use as a starting point would probably be:

• Amplitrex AT1000
  • Doesn't mention price, probably $$$
• Space-Tech Lab AudioTubeTester
  • Automatic
    • $1104: http://www.thebestamp.com/Testing_Equipment/AudioTubeTester-3.php
    • $380: Separate 300B extension
  • Manual
    • $784: http://www.thebestamp.com/Testing_Equipment/AudioTubeTester.php
    • $380: Separate 300B extension
• Maxi pre-amp tester and the maxi-matcher
  • Would need to buy two separate
    • $989: https://maximatcher.com/product/maxipreamp-ii/
      • Would also need adapter
      • $55: https://maximatcher.com/product/maxiadaptors-preamp-tube-adaptors/
    • $829: https://maximatcher.com/product/maximatcher-ii/
      • Would also need adapter
      • $149: https://maximatcher.com/product/52/

Any kind of comments from experienced people would be appreciated!

P.S. I'm not doing this to save money. I'm just a soul that always likes to drill deep into different topics.
