No advantage for distributed over bulk capacitance other than distributed capacitance sounds better in the case of power cords....Try it! 27Mhz will be passed by transformers through capacitive coupling of the primaries and secondaries, worse in the case of toroids and better in the case of high isolation EI types, due to substantially lower capacitance. Twenty years ago 27Mhz was the place to null and recently IBM said that the bulk of the problems are now in the 5Mhz region and most power cord manufacturers should have started playing with bulk capacitors to be used in conjuction with their distributed capacitance....Some component manufacturers are adding (or never stopped using) a small capacitor at the AC input and some folks are marketing a small capacitor (Quiet Lines) to be used to get the 5Mhz problem under control....Now what about the rainforests and world hunger?
