I can't comment on the other things you mentioned, Rich (lack of
but your reasoning seems poor here. The arc you mention has a point
of origination, and a point of termination. Both of these points are
are on physical objects inside the tube which are by necessity connected
mechanically to the outer envelope of the tube. Thus the arc doesn't exist
entirely in a vacuum (pun intended). And BTW, when the bang is due to
a parasitic oscillation what is the mechanism by which the loud bang is
generated? External arcing in the tank components?
