The Toshiba SC-λ 99 is a power amplifier engineered for the digital audio era, manufactured from 1982 to 1984 in Japan. It features advanced design elements, including newly developed complimentary service power MOS FETs that utilize a double diffusion structure called π -MOS, ensuring high voltage resistance, gain, and speed while minimizing on-resistance. The amplifier employs a dual FET cascode connection in the input stage, enhancing noise performance. A robust super Λ power supply system supports low noise levels and low impedance, thereby improving audio quality. The design includes a large toroidal transformer with multiple secondary windings to further reduce interference. Its circuitry utilizes high-reliability carbon resistors, various capacitors for noise reduction, and a servo-less DC amplifier design to preserve sound quality. The front panel features a large peak power meter with adjustable brightness and dual input terminals, while a unique clean drive circuit enables detailed monitoring of signal distortion. The amplifier also incorporates comprehensive protection circuits for both speaker connections and internal temperature management.
