hi,Bruce

I know very little abou all this. I trying to find out all I can on this. When I get time I will try to scan the paperwork I have on all this,and poist it.(I dont own a scaner yet, I have to use my cousin's.)Another thing is the instructions does not tell the length of wire needed on the primary, or the feedback just the secondary.So with out knowing the size of the toroid core itself its a guess.And does any one know if all toroids contain the same material?(Ferrite)Just wondering before I spend the time trying to wrap the core I found in my old computer. I unwraped the wire from it already it is yellow.I found it in the box where the power cable inters the (CPU).
