The Sansui Six Am/FM stereo receiver was produced from 1972 to around 1974. It retailed for $399.99. It was the smallest of Sansui’s single digit receivers and produced 34 watts per channel into 8 ohms. It also produced a very impressive 0.3% harmonic distortion.
The Sansui Seven, Eight and Eight Deluxe had more power and more features than the Six but the Six is a very well built receiver with plenty of power for a small room. It has an attractive wood case and aluminum face plate. The 4-gang FM tuner is very good.
One drawback to the Sansui Six receiver are the labels on the buttons. The glue holding them on tends to dry out over the years and they fall off. However, there are replacements that can be found on eBay.
The Sansui Six has a number of features that aren’t often found in small receivers. Dual phono inputs are one. Pre out/main in jacks, engraved writing on the face plate and indented tone controls are some others. And, as I mentioned above it has a real wood case. It also has provisions for a noise reduction adapter (Dolby) and a 4-channel adapter as well.
The Six was made in Japan and is all hand soldered. The amp boards and EQ board are socketed which makes it much easier to work on. The tone controls use selectors with fixed resistors as opposed to potentiometers which is another advantage.
The general consensus is that the Sansui Six has a detailed and refined sound that is both musical and punchy. The bass is not deep but is very fast and defined. A three-stage direct-coupled low-noise equalizer and a completely direct-coupled OCL pure complementary power amplifier help in this regard.
Overall, the Sansui Six is a great receiver for a smaller room. It is reasonably priced as well at around $300 to $400 for a nice working unit.
