Hi Adam,

The total capacitance should equate to 0.0469uF. This is fine for the coil 
size. The question is, do you have a transformer capable of charging the 
cap size within the BPS you'll be running? I assume you do. I ran various 
cap sizes (.02uF through .06uF) on a 13" sonotube with a 10kva PDT. The 
coil ran great!  I really miss that coil. David Rieben ran .085uF on his 
12" sonotube coil (a serious performer and a joy to behold!).

Take care,
Bart
