69 capacitors, 20 transistors, etc. have been replaced and completely overhauled! Sansui's popular premain amplifier. It entertains me with a powerful sound typical of Sansui from the 70s. The thickness of the mid-range is particularly attractive, and the impression is that you can hear a wide range of thick sounds, such as jazz, rock, and vocals. The exterior has dullness, scratches, etc. (ASAINE Tomonori)
