Richard, all

Thanks, I don't have any of the "fancy" stuff like Pearson CTs or Dual
storage scopes,  :^(       so I'll have to struggle for awhile with more 
basic equipment.   I agree that the losses are high; maybe we can, 
using suitable measurements, determine exactly where the losses are 
occuring, and how much in each component, to help optimize these
Tesla systems.  It will be most useful to separate the "wallplug-to-cap"
losses, from the cap to spark output losses.  In other words to separate
the the measurement of power supply losses from the RF and spark
output section losses.
