Hi Josh,

An obit has less power than you first coil. Try to find a 15KV 60MA neon
somewhere and build a Terry filter!

I'm building my second TC ever right now (first one was 5 years ago
my senior year of high school - used a 15kV 30mA NST and got around
27").  I'm wanting to make this one significantly more
impressive.  In my reading, I came across this:

<http://www.pupman.com/current/rstephens/mtc-a1.html>http://www.pupman.com/c
urrent/rstephens/mtc-a1.html

Robert filled his secondary with a dielectric insulating gas up to
+1.5PSI.  I'm assuming this was to avoid sparks through the interior
of the secondary?  Also, what's the importance of the pressure?

I'm not building anything extremely impressive.  I've just got an
18kV OBIT that doesn't have an amperage or kVA rating anywhere on it,
but I'm assuming it'll be ~25mA.

As a second question, how should I test the amperage on my
OBIT?  I've still not run this thing since acquiring it five years
ago...runs on 220.
