** Good point, Peter. If L-networks were resonant at the working freq.,
they would be a virtual short-circuit. To do their job, XC must not =
XL. A Pi-network is two L-networks in series. The apples/oranges glitch
is trying to relate a Pi-network Z-transformer to a parallel-resonant L/C
"Tank" - with a link output - Z-transformer.
