Testing 7868 on a Hickok 800.

[Carbsandcaps]

I’m trying to test a 7868 tube on my Hickok 800 tube tester but there’s no options for it. There isn’t even anything for the 7591. Nothing on the roll chart or the supplemental sheets. My b&k 700 will test both so I’m not up the creek but I was just curious if anyone knew a way of using the Hickok.

Pretty sure the bottom row of the B&K 707 is Emission test only.

Thought I read that in the manual.
