REPLY:
What do you call it? Good question. If I understand you right, you
have a simple parallel resonant circuit with the input on one tap and
the output on another tap. Correct?
Essentially, it is a resonant autotransformer. I have never heard that
term used before, but I think that describes it correctly.
