Hi everyone,

I was just wondering what people think about primay strikes because my small 
coil can arc nearly consistently to my primary coil.  I was wondering how 
bad this can really be as i have seen no damage yet.  Here are my coil's 
specs:

9000v 50ma(modified)NST

.0136uf MMC made from 2 strings of 10 in series, GE yellow snubber type 
caps.068uf each.  Each cap is 3kvdc, with the 10, i have a good 30kvdc 
rating(i really over built it!) so its very tough with my power level.

5 gap static gap.  Linear design of the Richard quick type.  Has a fan on 
it, about .25" total width.

Flat spiral primary, 9 turns .25" cu tubing.  Inner diameter-4", outer 
diameter-12", .25" spacing in between.

Secondary is 2.3" diameter x 10" wound with 28awg.  PVC form

Toroid- i have 2, 2" cord x 12" total diameter, stacked.

I can run the coil with a twin pri/sec setup, and have no problems with 
primary arcs, and get a nice 23" spark.  But with a single coil setup, i get 
strong primary arcs about 15" long(since they bow out a bit).

So are primary strikes really that bad?  I wanted to know because i may 
de-rate my cap to about 21kvdc when i get my small SRSG to work so that i 
have a bigger capacitance.  Since i do this, could i be putting my caps in 
danger,  im sure that with a SRSG, this coil will really go nuts.  Also, 
what parts of the primary circuit are at danger(if any) from primary 
strikes?

Steve Ward.
