Exceptionally beautiful vintage Sansui receiver with rare stand-alone CD-4 Demodulator included. This monster 4 channel receiver performs flawlessly and delivers incredible, crystal clear audio with plenty of power in all four channels. The build quality of this machine is simply unmatched, which is why it weighs almost as much as a tank. Recently serviced with all switches and controls cleaned and lubed for optimal listening conditions. The dial lights have all been replaced with new incandescent bulbs and the Stereo light replaced with a new LED. Cosmetically in excellent shape with the only noticeable wear being around the headphone jacks and an indentation on the top of the wood case (seen in last two pictures). These are virtually the only visible discrepancies. All the knobs and faceplate have been washed and polished to give it that showroom shine.  This baby comes with ALL the original documentation, including the original bill of sale from Japan in 1974, courier receipt to the US and the user manual and sales brochure. Also included is the rare CD-4 Demodulator adjustment vinyl record. You'll be hard pressed to find one of these in better condition, especially with all the documentation and service records.
Note to potential buyers: Please do your research and ask any questions you may have before buying to make sure this is the right receiver for your particular setup. This receiver has been tested and is fully functional at the time of sale, but it is an old piece of electronics and just like a classic car, requires a certain level of care and maintenance for continued optimal operating conditions. Everything I sell comes with a guarantee and returns are accepted if this item is delivered DOA or not operating as advertised. However, returns for other reasons including user error or buyers remorse are subject to a 30% restocking fee. This is a very large and heavy piece of equipment, measuring 23" long with another 5" with the demodulator at its side, so please be very sure this is the right system for you before buying. This particular receiver has many settings and a novice may think it's not working properly when it could just be on the wrong setting. Please fully review the included manual and all other documentation to familiarize yourself with this unit before using. This item is marked inside and out with unique serial numbers to deter fraudulent returns. Please do not take parts out or tamper with item and try returning it. I'm an honest seller and am hoping this goes to a good home. If you're curious about something please do not hesitate to ask. More item specifics below. Description

Uncompromising quality is the key factor in the design concept of the QRX-5500.

It's a full-fledged 4-channel stereo home control center with all the advantages of the very latest electronic technology in the form of its all-stage direct-coupled OCL pure complementary power amplifier.

What's more, it offers excellent performance, high fidelity performance of the highest standards, and Sansui reliability.

Sansurs revolutionary 4-channel audio developments, as exemplified by the QS regular matrix system with QS vario-matrix and the famed QS Synthesizer, is combined in this powerful 220-watt 4-channel amplifier and sensitive FM/AM stereo tuner to enable you to enjoy any and all stereo and 4-channel program sources in realistic 4-channel reproduction.

As in all models of the new Sansui QRX series, the basic secret of the QRX-5500 is its QS 4-channel Synthesizer and Decoder section, a team of circuits which together make up the new Sansui QS regular matrix decoder with QS vario-matrix.

The Synthesizer/ Decoder Control on the right-hand side of the front panel enables you to select any one of five different 4-channel reproduction modes, including Phase Matrix for decoding SQ encoded records.

There's also the extra excitement of hearing your favorite 2-channel music sources transformed into authentic 4-channel sound by the Sansui QS Synthesizer, now greatly enhanced thanks to the OS vario-matrix technique.

This, with the built-in discrete 4-channel tape and auxiliary input circuits adds up to full versatility in all 4-channel formats.
