Wes and all,

The original Brown-Boveri Journal paper by Guanella is reprinted in the book
"Classic Works in RF Engineering" (Walker/Meyer/Trask), which is available
from Amazon for ~$100. I wouldn't mind buying it - it looks pretty
interesting, and one reviewer says anybody working with HF magnetics should
have it. but I'm getting ready to retire and move, so another hundred bucks
on a book I'll have to move in a month or two is not recommended by the XYL.
Anybody have a copy?

FWIW, and 73,

Hi Alberto, and group,

The term "Guanella" balun is exactly the correct term for the thing
that we often call a current balun. I've been trying for 40 years
now to get a copy of the original reference. It is one of those
things that was published in an extremely obscure journal, yet it is
a paper that has become a central foundation for much of what we
do. Most frustrating.

Those were fun times with good people. I'm still looking for the
paper though.

I found a scanned copy of the original Guanella article from the Sept.
1944 edition of the Brown-Boveri Journal and have placed it in the
groups Files section.

The filename is guanella.pdf
