Funny. I went back and looked at the instructions and it calls the units transformers and calls the coils "prim." implying primary. Semantics.
The main issue is the coils are stagger tuned to cumulatively provide the wide bandwidth required. The shunting of the coils with the 330 ohm resistors is to effectively remove each tuned IF stage so that the response will be governed only by the tuner to 1st IF over coupled transformer link.
