Tuners after 1975 (catalog or manual is ---> here)

High-end and mid-range analog tuner
Year	Japanese model	Price	Band	Export model	Feature
1975	TU-9900	\89,800	FM/AM	TU-9900	Intermediate design of former and thereafter Sansui. The evaluation is still high in foreign countries. Photocoupler used noise canceller is also used for TU-D707 and TU-X1. It might be the last Sansui tuner to which the AM section was constructed discrete circuit.
1975	TU-7700	\65,000	FM/AM	TU-7700	Traditional sansui design face. Antenna attenatar and multipath-meter were equipped.
1975	TU-5500	\55,000	FM/AM	TU-5500	Traditional sansui design face. Antenna attenatar was equipped.
1977	TU-707	\54,800	FM/AM	TU-717,TU-710	Renewal old Sansui design. Simple, large window like modern architecture. It might be the last Sansui tuner to which the AF output amplifier was constructed discrete circuit.
1978	TU-D707	\69,800	FM/AM	TU-919	Similar face to TU-707. The circuit was changed greatly. Especially, FM circuit is subset or downgrade of TU-X1. Only detector circuit is as same as TU-707. Digitaly quarz lock was adopted. Reception freqency is displayed by LED. On the backpanel, FA-7 antenna, variable output, multipath detect, AM-IF output connector was added.
1979	TU-X1 (Japanese)	\135,000	FM/AM	TU-X1	Sansui's high-end tuner. FM and AM circuits are completely independent structures except power supply. The first tuner that adopt synchronous detector for AM. And only the tuner that adopt synchronous detector for AM. See Half about SANSUI FM/AM Tuner TU-X1 (Japanese)
Low price analog tuner
Year	Japanese model	Price	Band	Export model	Feature
1977	TU-107	\23,800	FM/AM	n/a	Thin design. External bar-antenna is omitted. I can't find corresponding one in oversea's market, although AU-117 amplifier was found.
1977	TU-207	\29,800	FM/AM	TU-217 (earlier ver)	Signal meter and bar antenna are added to TU-107.
1978	TU-307 (Japanese)	\31,000	FM/AM	TU-317 (earlier ver)	Noise canceler switch and panel illumination lamp is added to TU-207. Meter design is same as TU-107II and TU-207II
1979	TU-107II	\23,800	FM/AM	n/a	Meter design and logo were changed.
1979	TU-207II	\29,800	FM/AM	TU-217 (later ver)	Meter design and logo were changed. Model number was not changed in oversea's market.
1979	TU-307II (Japanese)	\31,000	FM/AM	TU-317 (later ver)	Logo was changed to white ground. Model number was not changed in oversea's market.
1979	TU-507	\39,800	FM/AM	TU-417	Similar appearance to TU-707. TU-517 has FM I/F band switch and 4 gangs. And because of meter panel design, TU-507 seems TU-417
1978	TU-D607	\49,800	FM/AM	between TU-719 and TU-519	Digitaly quarz lock was adopted. Reception freqency is displayed by fluorescent tube. Similar to TU-719. But TU-719 has Band Width and Calibration Tone switch Also similar to TU-519. But TU-519 has no digital display. And not "Quarz" Servo Locked Tuner
1979?	T-7000 (Japanese)	\35,800	FM/AM	T-80	Digitaly quarz lock was adopted. Reception freqency is displayed by fluorescent tube. Perhaps T-7000's Digitaly quarz lock with fluorescent tube freqency display unit is the same as TU-D607. As the FM tuner, same as or below TU-307. The circuit is similar to LUX-kit A808 (Although this is digital systhesizer tuner). AM circuit is simple discrete. Bar antenna built in the body.
digital synthesizer tuner
Year	Japanese model	Price	Band	Export model	Feature
1980	TU-S7	\48,000	FM/AM	TU-S7	I have no information or data.
198?	TU-S707X	\54,800	FM/AM
1984	TU-S707X DECADE	\54,800	FM/AM
1986	TU-a707	\??,800	FM/AM	("TU-a" means "TU-alpha")
1987	TU-a707i	\59,800	FM/AM
1989	TU-a707Extra	\54,700	FM/AM
1991	TU-a707R	\53,800	FM/AM

This list omit old tuners before 1975 and low price digital synthesizer tuners.
I have a few information about low price tuners. And there are a few information about them in the Internet.
Year of sale may be postponed one or two.
Sansui was not sell FM use only tuner.
Export model may be different from Japan's domestic model, although they have same model number.
It would be greatly appreciated if you inform of the error in writing and the omission, etc.
