The Technics SU-50A is a high-quality integrated amplifier that was first introduced in the 1980s. It is a part of the famed Technics SU-C Series, which was known for its exceptional sound quality and reliability. The SU-50A features a class AB power amplifier stage that delivers a maximum output power of 35 watts per channel into 8 ohms, or 50 watts per channel into 4 ohms. It also includes a phono stage for connecting a turntable, as well as several line input terminals for connecting other audio sources. One notable feature of the SU-50A is its unique "D-L Body" design philosophy, which aimed to create a compact, cost-effective amplifier while maintaining excellent performance. This was achieved through the use of advanced circuit design techniques and high-quality components, such as large-capacity audio capacitors and precision metal film resistors. The SU-50A has received critical acclaim from audiophiles and music enthusiasts for its rich, detailed sound, low-noise design, and excellent build quality. It is still highly sought-after today, with estimated prices for a fully restored and serviced unit ranging from $500 to $1,500. Overall, the Technics SU-50A is a true icon of vintage audio equipment, and a testament to the enduring legacy of the Technics brand.
