This is a PEARL VR-5 VOLTAGE REGULATOR. ※It is a power supply. The product includes the main unit and adapter. ※Box, DC cable, manual, and other items not shown in the images are not included. Power-on has been confirmed. It has a DC9V power supply outlet. The included adapter outputs DC12V/300mA, and can be used as a DC12V/300mA AC adapter on its own. There are scratches and dirt. It will be shipped via either Takkyubin Compact or Yu-Packet Plus. ※The shipping company may change depending on the circumstances, but the shipping cost and anonymous shipping will remain the same. I will not answer questions about serial numbers other than those shown in the images. #Effecter #PEARL #Pearl #PowerSupply #PowerSupply
