Coilers,

I have to say WOW!  Jeff's photos of his pancake & multilayer coils in
action ought to make us all think more seriously about alternate coil
architectures.  Bart - please let us know how your pancake secondary
performs.  And Jeff has also called our attention to the ancient massive
area quenched spark gaps which seem to work so well.  Someone ought to
combine the "Superquenched" gap design with triggering . . .
