Rare SANSUI 690 Receiver

The Sansui 690 is the European-market counterpart to the well-known Sansui 6060, sharing the same core amplifier architecture and warm analog voicing that made mid-1970s Sansui receivers highly respected among vintage audio enthusiasts.

Built during Sansui’s golden era, the 690 delivers a balanced, full-bodied sound signature with strong low-end authority, smooth midrange presentation, and refined high frequencies. Its classic brushed aluminum faceplate, solid tuning knob, and real wood cabinet reflect the craftsmanship and understated elegance of 1970s Japanese hi-fi engineering.

This unit has been fully restored and professionally serviced to ensure reliable daily performance while preserving its authentic vintage character.
