Any analysis of a power amplifier schematic must begin with the power supply, as it is the foundation of the unit’s dynamic capability. In the N7000 schematic, the power supply section is characterized by its heavy regulation and substantial energy reserve. The design utilizes a large toroidal transformer, chosen for its efficiency and low magnetic interference, which is critical in keeping the signal-to-noise ratio low.
