Maintenance information: 2024.11.17 Maintained (since the ground pattern of the switching SW solenoid had resistance, the ground was reinforced and corrected. Check the input/output waveform, check the left and right balance, and perform a comprehensive operation test by connecting the power amplifier to confirm normal operation. ※Unmentioned, it was confirmed that crosstalk was terrible. Treatment → Measures against receiving Hi from the input signal. (① The signal flowing to GND has been reduced. ② Anti-static resistors were inserted) 2022.9.17 Maintained (capacitors, semi-fixed resistors, relays, LEDs, lamps, ICs, and spark killers replaced. All SW, VR disassembly and cleaning. Resolder the deteriorated part of the solder surface of the board. (Check the input/output waveform, check the left and right balance, and perform a comprehensive operation test by connecting the power amplifier to confirm normal operation)
