Editorial

This edition of the eBook "Electronic Transformers" is based on the printed copy of R. Lee's book "Electronic Transformers and Circuits" published in 1955. As the copyright of this book has not been renewed in 1964 it has fallen into public domain (click here for more information on copyright renewal).

Although the topics covered in this book may seem to be outdated we included it into the VIAS ebook collection simply for its clear discussion of electronic transformers and related matters. Thus we took this book, converted it to HTML and compiled it into an introduction to general electronics, providing additional features such as links between the pages, an index, and a hierarchical table of contents. Further, we added a few new images, and converted the already existing images to a common style, so that the eBook can be regarded as a homogeneous and modern work, despite its considerable age.

At this point we want to thank Pete Millet who is enthusiastic about tube based electronics and who provided an extraordinary contribution to the electronics community by providing many old books as scanned pages. See his home page for more.

Finally, we decided to additionally publish this eBook as an MS Windows HTMLHelp file offering the same navigation structure as the Web-based version. We hope that this service makes it easier for many beginners to get acquainted to the field of electronic transformers.

Best wishes,
