I did check my stack of old paper and realized I am missing the
Guanella paper too! I would be really surprised if ABB still have a
copy of that article... BTW the HQ is in Switzerland, not Sweden!

What I do have is the following:

Some Broad-Band Transformers
C L Ruthroff, Proc of the IRE 1959

Wide Band Balanced and Screened Trnasformers
M M Maddox, J D Storer, Electronic Engineering 1957

Broadband Transfomer Desing for RF Transistor Power Amplifiers
O Pitzalis T P M Couse, Unknown Publisher Proc IEEE???

Designing Toroidal Transformers to Optimize Wideband Performance
H L Krauss C W Allen, Electronics 1973

These are all ageing copies, but I might be able to reproduce for
someone having interest in the subject.

GM Lasse. Another pair of wonderful papers on the subject, are the
Philips Semi application Notes ECO 7213 and ECO 6907. "Design of HF
wideband power transformers Parts 1 and 2". I don't have a URL for them
right off hand, but you should be able to Google them. If push comes to
shove, I can scan them and send them along, although probably better
done by snail mail, they're pretty comprehensive.
