Sansui, TU-9900 Iconic Flagship Tuner

This Sansui, TU-9900 FM/AM tuner is "the bomb"! I so wish WBCN & WFNX were still on the air cause this would be coming home with me, lol. The following is a technical excerpt from the 9900's owner’s manual.

"The TU-9900 thoroughly pursues the receiving performance of a tuner in order to ensure stable reception in all radio wave conditions. At the same time, the 9900 is an FM/AM tuner that incorporates excellent circuit technology and carefully selected materials in order to achieve both top audio performance and overall reception performance.

The front-end section uses a linear frequency type FM5 series varicon, three low-noise dual-gate MOS FETs, and one transistor. It is also equipped with an antenna attenuator switch, enabling stable reception even in long-distance reception areas and short distances with strong electric fields.

The IF section is equipped with a reception band switching function, so that both sound quality and reception performance are emphasized. A two stage 6-pole block filter with flat group delay characteristics is used for wide-band signals with an emphasis on sound quality, and a narrow-band 4-pole ceramic filter is used for reception with excellent adjacent interference rejection capability for narrow-band signals.

The ultra-wide-band ratio detection circuit and MPX section use a differential demodulation circuit and PLL (phase-locked loop) system with excellent phase characteristics, which provides good linearity over a wide bandwidth and a low distortion factor equivalent to that of a pre-main amplifier.

Equipped with an auto noise canceler that employs a photo-coupler. When a weak signal is input, the amount of blending to the left and right is automatically changed according to the signal level to cancel the noise, thereby improving the practical listening performance.

The AM tuner uses a double-tuned circuit and a Yaman type ceramic filter with two elements and two coils to improve sound quality and selectivity.

Each block stage uses a stabilized power supply with ± 2 power supply of good regulation to improve stable operation and sound quality. It features 3 dual-gate MOS FET, switchable sensitivity, signal generator and a low pass filter.

Built-in test oscillator for recording that can easily set the appropriate level on the deck." - Sansui, Ltd.

The TU-9900 is designed to match the superb performance of the AU-9900 and AU-11000 amplifiers. They made for a dynamic duo in there days but, if you remain an avid FM/AM listener, it's be hard to better that this iconic Sansui. It checks ALL the boxes by way of performance, look and overall vibe - an amazing piece for sure!
