Well, considering that you end up with a transformer wound on small binocular ferrite core, which has no less than ten leads coming out of it, I suspect that a few people may take more than one attempt to be sure they've got that right. My QA manager rejected the first one I produced. If you are not experienced in making such things, with bifilar windings, there is a learning curve. I wonder if a larger ferrite could be used to make things easier?
