Hi Steve,
You use the generaly accepted terms of primary and secondary. In common
 usage in the electrical sciences aren't these terms immediately associated 
with a transformer? That's the quesion  er, question.  If you look in Terman 
or any other similar text you will find many applications of a transformer in 
tuned circuits, but it is still the primary-secondary arrangement known as a 
transformer. Check out the book, The Complete Patents of Nikolas Tesla. See 
page 246 and neighboring pages. Our Founding
Father uses the same terms to describe the transformer action. A TC is a
tuned transformer.
