I agree. I am certain that the thing wasn't made like that & frankly I can't say for sure that EVERY tube tests good, but I notice that most do. That's when I break out the 'known good' units. Both a Hickok 6000A and the B&K Dynajet 747B. I read somewhere about a problem that will make a tester do what I have described, but I can't remember if it was the tubes or what.
