Full maintenance has been completed, including replacement of deteriorated vacuum tubes and capacitors! The original MC275 is the pinnacle of Macintosh tube amplifiers. A famous historical machine that intensely entertains music with its velvety luster and strong tone. Instead of resolution or wide range, the rich sound that makes you feel a sense of life is truly the Macintosh sound itself. ※The hood is not included. On the exterior, transformer scratches, oxidation, etc. are conspicuous. (YONEJIMA Satoshi)
