Power on was the only function confirmed. When a cassette tape was inserted and played, it rotated, but I did not confirm whether sound came out when connected to a speaker. This is an old product and has not been maintained, so it is being sold as junk. There is no box or instruction manual. Please check the condition in the photos. Due to a lack of specialized knowledge, I cannot assess the condition. This is a used item that has not been maintained, so there is a possibility of malfunction. It is considered a junk item. Would anyone who can use it for parts or repair be interested? As it is a used item, there are noticeable stains and scratches. Please note that we cannot completely clean it.
