hey that looks like a pretty good schematic.  Thanks.  Just a quick question 
on it:  The signal generator being the 555 does not show which prongs to 
use.  The 2N3055 transistors are pretty staight forward, but I can't figure 
out which of the 8 prongs to use on the 555.

this is the page that shows the schematic i'm looking at:
http://www.rmcybernetics.com/projects/DIY_Devices/homemade_tesla_coil.htm

Also, if I wanted to use more power, would I be able to use 120V AC to power 
the coils? (kinda like a small version of a NST)  Would i need heavy 
resisting or ballasting?  Could i just use like three in parallel to 
increase the voltage I can put accross them?
