It's always good to be lucky. Me, I can tear up anything.

Hey---

Our first TC in high school used 18 one gallon mayonnaise jars coated 
with al foil outside and salt water inside.  We later put foil inside.  
Pretty cumbersone, but they looked cool and made a nice buzzing sound 
and the corona around the edge of the foil was pretty.  They never 
failed.  Now I use a 0.05 uF 50kV Maxwell that has given excellent 
performance for 20 years with 3x 9/60 NSTs in parallel.  That gives a 
p-p of 25kV.  Pretty conservative.
