Yes, I have a Hickok 600A tube tester and it tests good
on that.
I got looking through my other type 80 tubes and I have
one other globe type (380) that also has a violet glow but it
is not nearly as strong as the first tube.
The ST type 80's I have don't show any glow at all.
I have been cooking the tube now for about 3 days and
the violet glow is still there... will keep you posted
on any further developments in my experiment!
