Thank you for viewing. This item was found while cleaning out my parents' house. Since the main unit is missing, I have not been able to confirm its operation. The exterior has no major damage and appears to be in relatively good condition, but since the operation has not been confirmed, I am selling it as a junk item. * The model number listed in the title (MD-ST600, etc.) is for reference only. * We do not know the compatible models, so please make your judgment based on the images. [Product Condition] * Operation not confirmed (treated as junk) * Due to being a used item, there may be minor scratches and small marks. * Everything in the images is included. [Please Note] * There may be oversights regarding dirt and scratches. * Please refrain from purchasing if you are sensitive to imperfections or seek perfection. * We do not offer dedicated listings. We appreciate your understanding and ask that you only purchase if you agree to these terms.
