Skip,

Correct,  I did take this into account!  The original reference was to
Wysock's model 10, I think! (its been snipped many posts back)  That was a
10kw coil!!  Thus the 200 watt resistor. (Reduced power dissapation)

Finally, field measurements are no good to compare to flaming arc channels
for voltage readings.  They may be related by some complex math function
which remains unknown at present, though.
