RE: [TCML] Still poor performance

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

Nothing jumps out as glaringly wrong, but not being able to see puts us at a distinct disadvantage!  Posting good photos would be immensely helpful.

For the toroid, how small is "smaller"?  The usual experience is that bigger is better, and smoother is better.

I don't think the primary connection matters.
