I really don't know much about this topic. My experience is much more 
"hands on" than it is technically-based.  And when I said "blew up," I was 
just using my own slang for a shorted tube, I didn't mean it literally.

And yes Keith, as you so tersely informed me, I do realize that one should 
use a tube tester in order to look for a well-balanced driver tube. I only 
joked about it since I don't own one. Would you like to send me one? God, 
that would be so great.
