mmc calculator

Hi All,
    After my mishap with my cap on Sunday I have decided to build a
bigger one.:-)) I have a few questions. When using  Barts java
calculator I am a bit puzzled about the" primary circuit resistance"
box. Do you use the single cap internal resistance calculation and
multiply it by the number of caps?. It looks to me as if there is a
trade off between  the voltage rating and the ESR. I have 340 of the ERO
caps that Mike got. 0.068uF 1500 volts. I know someone did find the spec
for these but I can't find it at the moment. I was going to go for  18
strings 0f 18 caps. If I use the single cap resistance calc this comes
out at 6.9 ohms. Which the program says is very good. Have I got this
right? I would like to use the same cap when I change to a DC supply. Is
the voltage calc the same.?

cheers
