I found one Maxwell pulse capacitor for $125 + shipping

What about four ceramic high-voltage transmission capacitors.  400pF @ 30KV.
I found those 4 for $30.  I will not be building any more tesla coils after
this one and don't really want to spend a fortune.  This is just for a
simple contest at work and has already gone way over budget.
The magnet wire for the secondary seems to be around $15 per pound and from
what I gather I'll need about 10 #s.  I believe 16 AWG is around 125 foot
per pound.

I appreciate the response.  I don't want to waste my money on junk but I
also don't want overkill.

Thanks
Malcolm
