Rotel RA1572

The circuitry draws on a high capacity power supply based on a Rotel custom designed and in-house manufactured oversized toroidal transformer. In addition to providing an abundance of voltage and current for all operating stages, the transformer’s toroidal shape helps prevent stray radiation patterns from corrupting audio signals as they pass through adjacent circuit stages. Subsequent power supply segments built with tight-tolerance parts including T-Network capacitors provide the exact voltage and current requirements to ensure stress-free signal reproduction.
