Abstract
The inventor has created several methods to eliminate or greatly reduce the ground loop problem. The inventor has discover that ground loop distortion is caused by the switching from positive to negative in alternating current. He has designed several devices to eliminate this problem. In his first embodiment he places a set of two diodes either cathode to cathode or anode to anode, or a neon bulb, or piezoelectric crystals in parallel with all the capacitors in an amplifier or other electronic device. These sets of diodes eliminate the ground loop distortion within the amplifier or electronic device. The applicant has also devises several power supply that eliminate or greatly reduce the ground loop distortion in an amplifier or electronic device they are attached to. Also the applicant has found that by attaching two diodes either anode to anode or cathode to cathode, or a neon bulb, or a piezoelectric crystals between an audio, video or digital cable and its ground will reduce distortion within the cable.
