DescriptionGrade : Used Operation has been confirmed with a supply voltage of 100V. There are some scratches. All my products are 100% Authentic. If you purchase an electrical appliance intended for use in Japan, you may need a step-down transformer (converter) to use it because the Japanese voltage standard is 100V. Please check the voltage display on the back of the product or on the adapter if one is included. In this case, the adapter display takes precedence. First, check the voltage environment you will be using. 1. If the adapter or product display (adapter takes precedence) is 100V, 100V-, you can use it in a voltage environment up to 120V. If the voltage environment you will be using is 121V or higher, you will need a transformer. 2. If the adapter or product display (adapter takes precedence) is 100V-240V, you can use it in a voltage environment within that range. If the voltage environment you will be using is higher than that, you will need a transformer. 3. For home appliances with built-in motors (such as turntables), use a transformer with a wattage 2-3 times higher than the adapter or product wattage (adapter takes precedence).4. For appliances that generate heat (such as vacuum tube amplifiers), use an adapter or a transformer with a wattage 1.25 times the wattage of the product (adapter takes priority).Watts/Volt-Amps (W/VA) = Volts x Amps Furthermore, the shape of the power plug varies from country to country. Please prepare the power plug along with the transformer. *We are not responsible for any damage caused by not using a transformer.Payment We usually ship within 5 business days of receiving cleared payment. Shipping We ship using FedEx, DHL.International Buyers - Please Note: Import duties, taxes and charges are not included in the item price or shipping charges.These charges are the buyer?s responsibility.Please check with your country?s customs office to determine what these additional costs will be prior to bidding/buying.
