Offered here: Sansui AU-719 integrated amplifier, built in 1981 with English user manual Service manual and construction schematic Various Sansui ' 70-ties and 80-ties ' brochures. Along with the pictures on CD-ROM Power: 2 x 90 Watts at 8Ω Frequency range: 5 Hz-70 kHz dimensions: 46 x 17 x 41 cm. Weight: approx 16 kg. Serial number: 229051490 This is High-End 1981. It is a good amplifier with the typical Sansui smooth sound, pleasant in the highs, neutral in the middle and a solid punch in the lows. The very reassuring “Sansui Click” of the speaker relay is characteristic, 1 to 2 seconds after turning it on. This fantastic sound quality in a huge frequency response is due to the very large food area with double transformer, the "DC coupled" construction which means no capacitors in the signal path that could have an inhibiting effect on the Pulse display. Very good match with the better speakers from that time like; Cabasse, KEF, B&W, Magnat, T+A and Celestion For Sansui concepts this is a Spartan equipped amplifier with a tone control that that has 2 switchable tilt points. All the vintage audio equipment offered by me is professionally checked and tested before taking photographs. A complete test is done by electro-technicians at this company. The devices have always been cleaned and repaired and re-adjusted where needed. The amplifier will be packaged twice, boxed twice in specially purchased boxes with a high load capacity.
