Serial C0175 (Sasaki Shota)
Maintenance information: 2023.4.27 Maintained by the manufacturer (battery has been replaced. The remote control was working properly, but solder etc. on the light receiving part have been strengthened just in case.
The small electrolytic capacitors in the control circuit and power supply circuit have been replaced with high performance and long life tantalum capacitors to stabilize operation.
The charging voltage, charging voltage monitoring reference, and voltage have been calibrated.
The level, distortion ratio, and residual noise of each input/output were measured and confirmed that they were reference values.
*When you have finished listening on battery operation, quickly switch to AC mode manually to maximize battery life. When unplugging the AC cable, be sure to perform a reset by pressing and holding the center button on the power supply unit. We recommend staying connected to AC power whenever possible. (Please be aware that deep discharge and long-term storage may cause serious damage to lead batteries, even once)
