Nice work, Steve! Do post a picture if you have one. Not sure if the "contra" approach will be as revolutionary as the name has historically implied, but it does hold promise for flexibility and performance.

Hi Jerry,
There isn't enough room on the rod to use larger Litz and still have enough space to mount the rod unless 40/44 Litz is used.

Steve, wow, what a great idea. Can you provide a Picture and a bit more detail re the wiring details re the connections to the PL 380? Also is this setup only for the 40/44 Litz Wire, or would this also work for the heavier guage 100/44 Litz Wire?
