Re tiny spark: All that occurs to me is that you may have a shorted out
transformer. Do you get a nice snappy spark across your gaps? If you don't
there is likely to be something wrong. Perhaps you have a short in your caps
that needs the higher voltage to punch through. Check the output of your
transformers (without the caps in the circuit). You should see a nice fat
spark that peaks in the middle like an inverted V. If you see a small squeeky
spark, it indicates that something is shorted out or out of phase.
Re caps: If you didn't pay too much for them and you only got them for coil
use, I say go for it. The dc voltage rating works out to about 1/2 to 1/3
(depending who you ask) of the AC voltage rating. Therefore, your caps are
good for between 8300V to 12500V. I keep hearing use 1/3 the DC voltage
rating, but I have gone to 15kV on 30kV DC caps without problems.
