Sansui model TU-517 AM/FM Stereo tuner in very good condition. Little brother to the TU-717, the TU-517 has all of the important features of that model including outstanding sensitivity, low distortion and narrow IF bandwidth mode. This unit has been serviced and fully tested. Our original Performance Verification Report included.

From Sansui:

The reception and the reproduction abilities of Sansui's prestigious TU-517 stereo FM/AM tuner are both strictly Hi-Fi.

It all begins in the precision FM front end, featuring a low-noise dual-gate MOS FET radio frequency amp and a newly-designed, precision frequency-linear, wide-gap 4-gang tuning capacitor.

The latter has more frequency stability and more accuracy for tuning-dial calibration. And overall, the TU-517 achieves an amazing sensitivity to incoming signals.

Objectifying this claim is easy. The TU-517's 50dB quieting sensitivity, for instance, is a high 34dBf (stereo). As you may know, this specification relates to the strength of the incoming signal required for the tuner to achieve a signal-to-noise ratio of 50dB or better. It is a truer measure of high fidelity quality than the old parameter tied to an unsophisticated 30dB S/N. The 30dB S/N is hardly Hi-Fi. since it allows for as much as 3% distortion in the reproduced signal.

Helping to achieve the high 50dB quieting sensitivity of 34dBf, as explained above, are the ten differential amps formed of five ICs in the FM IF section of the TU-517. But the main advantage here is in superb selectivity. It's ability to receive only the station you want while rejecting all others. is a high 50dB. This is true even when the selectable IF bandwidth switch is turned to wide.

There are not a few tuners which have this ability to pick out a single station, even in the face of neighbouring stations of higher transmission power. But poor distortion performance usually accompanies this high selectivity. In the TU-517, neither reception nor reproduction quality is sacrificed.
