This is a unit that could not be repaired even after replacing the capacitors, and has defects due to problems with other chips, etc. The capacitors have been removed, but most of the internal circuit board is still present, so it can be used for parts. Only two screws are attached for easy disassembly, and the rest are placed in a bag as shown in the photo. Approximately 50g worth of parts are included. This is a completely junk item, uncleaned and with damaged parts. Please refrain from reselling it as a product with unconfirmed operation. It will be shipped simply by placing it directly in a cardboard box. The plastic of the main unit has deteriorated and may be damaged during shipping. Please understand this.
