The Toshiba SB-A10, released in 1981, is an integrated amplifier designed as part of the Aurex micro-component series. This compact model measures approximately 20 cm in width and is characterized by its sleek silver finish. The SB-A10 incorporates a 2x20W output at 8 ohms, which, while relatively modest, was considered efficient for its size. Designed with a conventional Class AB amplifier configuration, the SB-A10 features a toroidal mains transformer for power. Its internal architecture includes a fully complementary output stage with a dedicated low-level gain block for tone control adjustments. The amplifier also possesses phono stage designed for MM cartridges, a microphone mixing input, and standard linear inputs suitable for various source components. The controls are composed of machined aluminum, signifying a choice for durability over a plastic alternative. Despite its smaller size, it provides a range of features typical of larger amplifiers, including a tape loop and headphone jack, making it versatile for a variety of audio setups. The overall construction reflects a balance between cost-effectiveness and quality engineering, allowing it to compete with larger, more expensive systems.
