I found your article very interesting and very in depth. I am not interested, at this point, in mass production. My question is about the electrical characteristic. My calculations involve inductive reactance rather than number of turns. What is going to be the drawback in my shortcuts to building the stepup autotransformer? Is there any wrapping that goes between the core and the winding?

I was able to construct the autotransformer with a couple of drawbacks. It turns out that I had to solder the magnet wire together and tapping it is difficult when it is already wound. I was aso too lazy to make the wire large enough to handle the current. We will see if this is the case.

Kevin, when I mentioned that you might want to send a personal message to the author of the article, I was referring to the "instant message" feature. Click on his name in one of his posts and you will be able to send him a personal message from this site.

It turns out that my autotransformer did not have enough reactance to keep the power outlet from blowing the fuse. I did, however, keep the windings intact. The inductor that it turned out to be is a good power inductor with a less than perfect equation. If anybody is curious I will explain a little further how I did it.
