Their server seems to be down today.( I kept it in my bookmarks for parts and it won't come up). Just save the link for now and look later.

These are more expensive,  but the permeability is way less than what the site Hazens posted quotes. u=60 and u=125 Who knows ?

They are a greenish color and are called chokes. I think it is where MK1's toroid may have come from. Or something like it. These cost 35 but the shipping was 12 so $47 all together. I waited to know I couldn't get the cheaper kind from other sources to work as strongly as MK1.

I will let you know. I am sure you know that by now!

@jesus,
I would like to make your circuit mostly because it is so clear, but I don't want to make it if you have not tried it yet.

I am being overly cautious, maybe but I do not want a battery to explode in my face because I am giving it 100 times too much because I am making a little mistake with a diode.

I do know, and thank you Jeanna.  I haven't been posting pics lately because my camera is packed away for my much needed vacation.  My latest coil seems good.  I keep messing with it and let me tell you trimmers can really help you find the right resistance, I'm getting about 377-380vDC out of it and can power leds galore, neon's, DC motors etc.  It's not strong enough for a ccfl but I'm getting there.  I have been using supercaps but I want to put them in parrelal and I also want to add a voltage multiplier.
