RE: [TCML] Interesting Coil Wrap

["Lau, Gary" <Gary.Lau@xxxxxx>]

I'm not sure if I'm exposing my ignorance or what, but I didn't think that bipolar secondaries were wound any differently than conventional ones, as far as each half being wound in a different direction.  Did I miss that?

Thanks, Gary Lau
