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. 73 Lasse SM5GLC

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. W4ZCB
