The resistors are placed across each stagger tuned coil. There is really no primary and I don't know why you are hung up on that. There is the stagger tuned coil and the parallel tuned trap mutually coupled to it. It is clearly identified on the schematic.
Do you understand what you are doing by clipping in place the resistors? It is to eliminate the resonance of the stagger tuned coils so that the remainder of the video IF strip is just an untuned amplifier. This is so you can see independently the tuner over coupled transformer link frequency response when you sweep it. You must try and understand the process so so will be better able to identify and rectify any problems.

So the "resonant coil" in this example (T-106) is the coil that's in circuit?

I'm confused. Can you clarify for me the difference between the resonant coil and the stagger tuned coil? You refer to the "stagger tuned stage". I guess that's confusing to me as well.
Basically I think I need to know what is in these cans. For the pictured T-106, the can is literally the stagger tuned stage? The 2 coils within it...the coil between D and C is the resonant coil. Is this correct? What is the other coil, the one that stands alone and is not connected in the circuit? Or am I looking at this the wrong way and I need to think of the 2 coils in the stage as a single item?
