A choke coil [e.g exceeding about three (3) henries] placed in parallel with the A/C line, that is, preferably across the A/C line's "hot" and "common" lines, quenching the reflected signal (or back emf) that is developed when any power amplifier or other load places it's demands upon the incoming A/C power line. Due to its electromagnetic characteristics, the choke tends to provide a momentary high current source of energy when needed by, e.g., a power amplifier (or other appropriate load) when transient demand is called for. The invention's parallel choke approach, due to the fact that it must be magnetically charged by electricity [either from the A/C line or back electromotive force (emf) from it's load] tends to have a reversing effect on this signal, preventing, eliminating or at least substantially reducing it's presence on the A/C line, thereby providing a greatly enhanced A/C power line signal quality for the load. Without this choke, the otherwise untreated signals are able to modulate the A/C line, as it is resistive (basically a wire going from the utility services transformer to the wall outlet into which the load(s) is/are plugged). Exemplary applications include A/C operated, electric or electronic equipment, preferably, e.g., audio power amplifiers and preamplifiers, televisions, computers, computer peripherals, and other such electronic component equipment or other electrical equipment or devices, for example, electrical motors, air conditioners and other major and minor appliances, etc. |
