John,

What about the capacitance of a wirewound?  Wirewounds are usu. wound as a
loop folded in half on a former to reduce inductance (small loop area) with
the beginning and end of the loop touching thru a dielectric (glass, enamel,
carbon, plastic, etc).  You get a capacitance bypassing the inductor and the
resistor!

Ever see or measure that?
