I have two 15kv 60 mA neon transformers that I will be using to power the
beast. I plan to use my caps in series/parallel arrangement- I just hope like
heck that they dont blow. I made the caps using 1.5 mm (60 mil) thick
polyethylene so technically they should be good for the voltage.
Thanks for the advice on running them in gently - I will definitely do this.
BTW- how did you blow your caps? I know you were trying to max out your coil-
do you reckon that you set your spark gaps too wide? Was it the same thing
when your neons blew as well ( I sure dont want to blow my neons either- I
couldnt find any old ones around so I bought 2 brand new imported Italian
neons - they cost me about $150 US for the pair!)

Ok I will definitely be keeping the safety gap.
Well things are finally starting to come together now- hopefully I will be
producing spark (and not smoke from my caps or neon) in about a week or 2.
(BTW Ed, I have to admit I am really impressed with how fast you have been in
making your Tesla coils- I still remember your first post from when you were
just starting to make your first Quick assisted neon power coil, and just a
few months later you are using pigs to power them!
