All 4 output tubes have been replaced and maintained! Luxman's new generation vacuum tube power amplifier. Unlike the sound made by vacuum tube amplifiers in the old days, there is little sweetness, and you can enjoy crisp, tight sound quality, and a deep sense of density that cannot be obtained with transistor power. The response is also agile and the amplifier has a sense of speed. Since it comes with a volume, it can also be connected directly to a CD. There are spots and small scratches on the exterior (Wang Zhan)
Maintenance information: 2026.5.22 Maintained (4 output tubes replaced. Input volume exchange. Disassemble the input changeover switch and apply a protective agent for polishing and cleaning. Capacitor and resistor misalignment correction. Vacuum tube pin cleaning and foreign matter removal. The bias was adjusted, the output sound was checked, and the interior and exterior were cleaned. *There is no problem with the bias volume. (Because of the large, highly reliable sealed adjustment volume, some torque is required to turn)
Accessories: instruction manual, power cable, original box
