The Sansui TU-517 is a nice looking, well made tuner with true audiophile standard sound quality that beats virtually all modern tuners regardless of price. It was almost identical to the slightly more expensive TU-717 with outwardly the only difference being the absence of a calibration level switch (to aid setting of recording levels on tape decks) and LEDs to indicate the selected waveband. The internal circuitry inside a TU-517 is virtually identical to a TU-717 and they sound identical. The TU-517 is the better buy as they tend to be significantly cheaper on eBay.

The TU-517's tuning capacitor. Note the 4 FM gangs and the 2 AM gangs.

Like all Sansui's amplifiers and tuners manufactured in the late 1970's the TU-517 has a thick aluminium front panel painted in matt black. It looks tasteful but the paint finish can be easily chipped/scratched when subjected to careless handling. When new, the TU-517 was supplied with professional style rack mounting handles to allow mounting into a 19" equipment rack. The rack handles are attached to the sides of the unit by two screws and are of course detachable.
