Maintenance information: 2024.4.15 Maintained by the manufacturer (after fixing production issues, measurement and aging (5H) were completely reworked, and the 300B1 was replaced due to poor output (insufficient output). Since this product is a circuit with a transformer arranged at the input part, the input impedance is designed to be lower than a normal vacuum tube amplifier. Therefore, we recommend using the input volume at the maximum position unless there are special circumstances)
