Rare big Pioneer, totally working perfect. Cleaned in and outside. New flicker free led illumination. Good stereo reception 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. De-oxide was not needed. All lamps are original and working. For reliability the input is set to "240V" and bias is set correct. Very good stereo reception. Original manual and schematic.
