Interesting thought.

Agreed. I don't actually claim that chaos has anything to do with the
problem. (I get carried away when I'm having fun.) And I freely admit that I
have limited knowledge of tube dynamics, which limits my ability to make a
constructive case in favor of weirdness. I have been reacting mainly to the
sweeping assertions of stability that I've read by pointing out how hard it
is to be really *sure*. Maybe I'm just too old to be sure about anything!
Well, I'm pretty sure the sun will come up tomorrow. The best statistical
evidence to date gives odds of about 10^12 to 1.
Thank you for the lengthy and thoughtful summary, Ian. It had far better SNR
than most discussions in this group!
