Rare find, totally original and working perfect. The receivers marked with the SX symbol are Pioneer’s flagship products from the 70s. They are characterized by a beautiful, warm and rich sound, as well as extremely solid finish. Still, it is the SX-X50 series receivers that boast the highest quality among Pioneer’s models of that era. The SX-750 is a Pioneer receiver from the second half of the 70s, characterized by high efficiency and clear sound. This model is also an extremely “musical” device with soul. Just as the entire flagship SX series it stands out thanks to its beautiful, warm and juicy sound, as well as a high-quality finish. Potentiometers and switches in perfect condition.
