Those things we call a "current balun" are common mode chokes. W1HIS's paper 
is good, but my piece has MUCH better measured data on these chokes and how to 
wind them. There are some SERIOUS measurement errors that are the basis of 
W1HIS's work, and they cause his recommendations for how to wind chokes to be 
wrong. Otherwise it's a very good piece. 

BTW -- I recently got email from W2DU, who had just read my tutorial and liked 
it a lot. If you haven't been there, his website is well worth the visit. It 
includes several chapters from his book "Reflections." They are excellent.
