Well he has 13 of them. 13*500E-12=0.0065mf, which is what I need. Now, the
question is will these cap resist the 12KV AC if they are made to resist to
20kV DC. If I'm right, the peak value of the xformer would be 16.5KV... I
think if the cap is rated for 20KV DC, it should resist the 17KV (peak) and
maybe more with the kickbacks. What about buildin a second safety gap at the
caps???
