I'm selling this because I changed my audio equipment, even though I bought it about a year and a half ago. -It was kept on a shelf, so it's in very good condition with no scratches. -The vacuum tubes have been replaced with US-made GE JAN 5654W tubes instead of the original ones. The resolution is higher than the original, and you can enjoy swapping them out to suit your preferences. The original vacuum tubes broke during storage, so I'm including the remaining one as a spare. -Included: Power cord, Bluetooth antenna, one original vacuum tube (pictured) -Bluetooth connection is available (operation confirmed). -3.5mm headphone output or speaker output -Size: 12.9 x 9.8 x 3.4 cm -Original price: ¥14,527
