I think you are wise connecting the resistors 78 and 79 and shown in the schematic. One other thing that occurs to me is that with the windings of the transformer, they form an RL circuit, and become a path to ground for interference. I think the caps serve to further filter RF to ground, as morzh observed. I would recommend using them as they are shown in the schematic.
