John -

Note that 1.7 amps x 120 volts is 204 watts. The 15/30 NST output is 450
watts. Output greater than input? Something is wrong.

Hey coilers,

I just received my order of some motor running caps today from USA
manufacturing http://www.usamfg-dot-net/ that someone on this list recently
recomended.  When I checked my 15/30 NST a few weeks ago it was drawing
about 8 amps!  I checked it today prior to adding some PFC caps.  It was
down to about 6.5 amps.  Must have been more tuning I did since the prior
check I guess.  Anyhow, I added 40 ufd (170vac) PFC caps one at a time to
the NST primary.  Each cap I added reduced the current by about 1.5 - 2
amps.  I stopped adding caps once I hit 120ufd (3 caps).  With these 3 caps
my current draw was hovering between 1.8 and 2 amps with an occasional low
end of 1.7 and a high of 2.2 amps.  From messages on the list I did not
expect this much of a reduction but am very pleased with the results.  Not
to sound cocky but as far as efficiency goes is 2.2 amps line draw from my
15/30 NST system that puts out sparks into air about 34" and has given me a
max to ground of 39.5" kicken some major butt or what?  Looks like lt's time
to replace my fuse with a smaller one.  Thanks again to John Freau the
"efficiency guy" for all his tips.
