This power amplifier is an improved version based on the 405 model, featuring a slightly more modern sonic character. Despite its compact size, it offers calm, rich tonal quality. Unit was professionally overhauled in January 2023. Please note that depending on the manufacturer's design, an output mute relay circuit is missing, so a slight ignition pop may occur, which is not a defect. We are located in Japan. For electrical products, check the manufacturer and product and convert them based on each country's voltage. Please note that we have many second hand (100V) products used in Japan for sale. If you have any questions, please feel free to contact us at any time.
