【Rare! SONY TA-F333ESXII Integrated Amplifier】 A masterpiece perfect for those seeking high-quality sound! Capable of freely controlling powerful bass and delicate treble. Condition: Sound output confirmed → CD AUX Connected to speakers. No crackling was observed. Pressing the source direct button sometimes caused a momentary noise, but overall, I believe it's producing good sound. Occasionally, the left and right channel volume balance was different during low-volume playback, but this was corrected by adjusting the volume. The headphone jack is loose. I haven't been able to confirm its functionality due to my current environment. I don't think there are any noticeable scratches on the exterior (please check the photos for details). A must-see for audio fans, a rare vintage model! Please consider purchasing it soon!
