Miraculous beauty! Like new, fully maintained! Sansui high-end integrated amplifier AU-α607DR

Miracle! Truly beautiful! Fully refurbished, like new!
This is a Sansui high-end integrated amplifier AU-α607DR.

The exterior was dirty, but thanks to professional repainting, it shines with a brilliance that belies its 30-year age.

Normally, electrolytic capacitors deteriorate after 30 years, but there is almost no degradation, proving its low usage.

Functionally, it has undergone maintenance by an audio specialist.
The maintenance includes reinforced crack soldering, contact cleaning of switches and volume controls, exterior cleaning/repair, and circuit checks using an oscilloscope and tester.
The sound output is balanced on both the left and right channels, with no distortion or crackling.
It produces the soft, expansive sound characteristic of Sansui's high-end models.
