Hi, I would just like to correct your assumption on the Orange tube tester.

Yes you can match power tubes with the unit, it's one of it's features. it has a bold and straight to the point matching system.
You can also test for the matching in dual triodes (12AX7, 12AU7, 12AT7)

This unit is marketed towards the musician and not the electronics tech, so it's dead simple and easy to use.
What are orange matching tests, or matching assumptions I don't really know, but I used it quite often to match power tubes, and when I plugged the tubes into a Push Pull amplifier am biased the amp the current consumption was quite similar between all the output tubes, so it seem to work.

For a time I had the Hickok 6000A tube tester and the Orange VT on the shop, so I tested same tubes on both, results were not consistent between the 2 units, Orange seems to "Fail" more tubes than the expensive Hickhok, so then I was just confused in which unit to trust.
Anyway you cannot match tubes with a tube tester, even if you have an expensive tester like the Hickok or the Avo MKIV, but you can for sure get some level of matching that works well in real world with the Orange VT.

Anyways if you really want to get into tube matching, the only way of doing it properly it's with a Curve Tracer.
I also recommend the Utracer that was mentioned in this thread already.
