Collector’s model.  The device is in perfect condition!
In our projects we do not use veneers that are thin, unreliable and, above all, not resistant to damage!
We use only the highest quality veneers,  i.e. wood sheets of 3-5mm thickness. Thanks to this solution and the bonding technology we have developed, our products are equipped with durable and beautiful enclosures.


Pioneer SX – 737 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 SX series receivers are Pioneer’s flagship products from the 70s. They have a beautifully warn and rich sound and an incredibly solid design. The SX-737 from the same series is an example of quality over quantity. Despite its medium power, it is characterized by very high efficiency and exquisite versatility. It is equipped with cutting edge solutions of its time that ensure perfect sound quality to this day. The SX-737 is a high quality stereo receiver with a power of 35W per channel at 8 Ohm and a frequency response ranging from 15 to 40 000 Hz, as well as a total harmonic distortion of no more than 0.5%. The FM tuner is equipped with a 4-times linear frequency variable capacitor with and a dual MOS FET gate. A multiplex demodulator with a revolutionary PLL (Phase Lock Loop) circuit enables a new dimension of FM reception stability. A precise SX-737 phono equalizer keeps RIAA deviation within +- 0.3 dB.

The enclosure has been completely revitalized, made of American walnut wood. The wood finish is Chinese oil produced from natural oils and natural turpentine-based beeswax. Potentiometers in perfect condition. The metal elements of the enclosure have been cleaned and painted using the automotive wet painting technique. The device has been fully revised and serviced, equipped with new aluminium legs.
