If you need a center tap for balanced operation, please explain why Jensen and Neumann, both
highly respected in their fields, omitted it. This is not rhetorical; I'm interested in what you are able to find from these manufacturers.
Bill Whitlock wrote a book while working at Jensen. On

needed isn't given much consideration...
At this point I've proven that a center tap isn't needed. That means that the idea that it is needed is simply a myth.
