Thank you for taking the time to type all that out. I had never heard this before, and a few years ago I was trying to match to the input and output of some old Allison Laboratory audio filters I had come by. They require a good match in order to work to spec. I now see that my thinking back then was in error! Now, let me see if I've got this straight. I have a primary with a stated rating of 1000 ohms CT. I connect my signal across the whole primary, (i.e., the outer leads or pins). If I don't ground the CT the input to the winding will see appoximately 2000 ohms impedance. If I ground the CT my input impedance will be the rated 1000 ohms. How am I doing? (I used to think, and Mouser thinks, that an input connected to either outer pin and the CT would see 500 ohms, and connected to the two outer pins only it would see 1000 ohms. The CT was kind of "out of our thoughts".)
