Please read the following and make your purchase. 【Product Description】 Product Name: PDM/R Brand/Manufacturer: Classic Pro 【Condition of the Product】 There are some scratches, but I think it's in good condition. In my environment, the power turns on without any problems, and the voltage is displayed. The reason for being junk is that when the power is turned on, a small "don-don" sound comes from inside. Also, the Extreme Voltage lamp is on, and it is receiving power. The output regulation LED (lights up when the output voltage is normal) does not light up, but the voltage display is normal. All outlets are powered. Due to the above condition, please purchase only if you have knowledge of electricity and this equipment and can make adjustments yourself. When connecting to external devices, it is recommended that you check with a tester yourself for safety. It can be used in its current state, but please consider it as junk. No warranty. We will ship quickly with air-cushion packaging and corrugated cardboard. Thank you.
