Re: [TCML] Sphere Topload Coil

[bartb <bartb@xxxxxxxxxxxxxxxx>]

Yes Terry, that sounds like the one I was thinking about.
Some very decent sparks with that big sphere! I expect it was hard to 
break out as I've run a 2 foot sphere myself. Yes, a lot nice pictures 
and I'm killing myself now that I can't find any of those on my hard 
drive (not like me to not save cool photo's. Well, my brain never forgot 
anyway).

Take care,
Bart
