Excellent job done by Mr. Harris in providing many valuable resources for
transformer knowledge. Thought I might add one or two additions to his
already excellent list.


Electronic Transformers and Circuits
Third Edition


Reuben Lee, Leo Wilson, and Charles E. Carter


John Wiley & Sons, Inc.
605 Third Avenue
NY, NY 10158-0012


ISBN #0-471-81976-X


This is an excellent reference book...written by one of the masters. The
orig manuscript was published in 1947 and is "collectible" amongst tranney
enthusiasts (yeah...I know there's only a few of us!).


Norman Crowhurst wrote a ton of books and articles...anything by this guy
is really top flight. His books of nomographs are especially useful.
Check these out and send me your duplicates .


On a slightly off topic note....wonder how difficult it would be to write
computer programs that would replicate the nomographs that Crowhurst (and
other authors) did many years ago. Be neat to just punch in the necessary
variables and let the computer rip through the problem in two seconds
flat.
