A regenerator, or something comparable, is an absolute must for my situation. This building is riddled with code compliant wackery. Code compliant because building codes did not exist when this old girl was built. Ground loops on catv, phone, and satellite. Knob and tube lighting mixed with receptacles. Pumps without a neutral. Real shit show. I was thrilled to learn about regenerated power and it’s audio application. Everything, including amps, are connected. What came as a surprise was connecting the amps and not pushing the regenerator into the red. It handles power needs far beyond spec. System background noise and power noise fade to black. A wonderful addition to a system.
