You are shunting each of the coils.
Do you understand why you are shunting the coils with the resistors?

No you have lost me. I guess transformer is the wrong term. I don't know what "capacitively coupled" means. I think the purpose of the traps was discussed before and at one point I had the concept but now I'm not sure. I think I remember they were to "trap" and eliminate certain frequencies from the video signal minimizing interference but the only one I recall being discussed was T-103 and the 21.25MHz trap.
There are a lot of terms I listen to without completely understanding them. I know the standard definition in everyday life of the word "coupled" but in electronics I'm not so sure. Most of what has been talked about leads me to think when 2 things are "coupled", one affects the other despite not being directly connected. Is this correct? Capacitively coupled??? Nope. Loosely coupled??? Nope
