Tube tester...anyone own their own?

I own, and like very much, the Amplitrex tester.  It is a modern design that is still in production.  It's ease of use is unmatched.  One chooses the tube type from a menu, and after a type is selected, the display tells you which socket to use.  The machine then warms up the tube before testing.  The screen showing the results displays the specification for the tube, which can be compared to test results, and also interprets the results as strong, weak, etc.  The tester measures emissions, transconductance, gas/leakage, and noise.  The Amplitrex tests at full power to stress the tube; this gives more honest results than the vast majority of units that do not stress test the tubes. A lot of tubes that test strong on a Hickok, for example, will not do as well on the Amplitrex.

For tube types not on the menu, the unit can be programmed to test such other tube types.  For really advanced users, it can be hooked up to a laptop and it will then curve trace the tube.  

The downside is, primarily, that the Amplitrex is expensive.

A local dealer uses the Orange to do quick screens of small signal tubes and EL84 output tubes.  It is much easier to use than the TV-7 that is the main tube tester in the shop.

One more thing about the orange—it fails far more tubes than a Hickock.  I don’t know if that is good or bad.
