Description
Pioneer SX – 850 receiver. Classic Vintage. Fully revitalized.
In 1937 Nozomu Matsumoto created the first magnetoelectric speaker in Japan, and a year later, in Tokyo, he registered the company under the name Fukuin Shokai Denki Seisakusho. In 1961, the company’s name was changed to Pioneer Electronic Corporation. However, the breakthrough came in 1962, when the company entered the Tokyo Stock Exchange and created the world’s first stereo system with speakers in separate housings. Four years later, Pioneer opened branches in the USA and in Europe. In 1978, the company created one of the best-known and most powerful receivers in its history SX-1980. Pioneer can also be proud of great successes in the world of auto-moto, as it introduced in 1975 the world’s first automotive stereo subassembly, then in 1984 a CD player and GPS navigation in 1990. The company also played a major role in the development of DVDs, plasma TVs and technologies Organic LED display (OLED). The company is currently part of Pioneer & Onkyo Corporation.
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.
Pioneer SX-850 is a powerful device, with a very quiet phono equalizer and a highly selective tuner. This model is also extremely sophisticated, which helps to fully profit from its power of sound, without compromising on its musicality.
The model has been equipped with a new enlarged walnut wood enclosure, which brings out its beautiful design characteristic of the 70s. The wood finish is Chinese oil produced from natural oils. Potentiometers are in perfect condition. The metal parts of the enclosure have been cleaned and painted using the automotive wet painting technique. The device has been fully reviewed and serviced.
Collector’s item. The device is in perfect condition. New yellow illumination of the front panel.
