I asked this same question when i first got started. I always wondered, why 
are these people wrapping these tubes, just use a solid metal tube. Well, 
the reason is, if you had i solid tube of metal, the ratio of your 
transformer would 10:1. 10 turnes being the primary, 1 being the secondary. 
You would get about the same voltage in you put out (well, i think the 
same). When you wind you coil, you are making it 10:1000. This way, you 
have a transformer. I think someone could probally describe it better, but 
it made sence to me.
Thanks
