What about a 9kV 60ma NST, still too little power to drive that large of a
secondary? I have a bit of difficulty getting my hands on transformers, I
was lucky to find this OBIT at a pawn shop for like $50 (alot of money for
if IMHO). I *may* be able to find a 9kV NST, but chances are slim. My
budget
is the second constraint..... Very constraining - I would like to ( read:
In
my dreams I) build the whole thing for under $100. I was finnally able to
get a farm equipment store order in the wire for me, it should be here
tomarrow, they are just takeing what I need from a 10Kg spool, and this
could be expensive (even though its only like 2000ft). The table I used
suggested a 4:1 ratio for a 24 inch coil, indicating 8 x 24, however, what
would happen if I were to, say, do it with a 6 inch diameter, or even
smaller? would there be serious performance degredation?, is there an
alternate ratio chart I can use? Any help would be appreciated.
Thankyou,
