【Product Name】 TAPEX 5.1ch Dolby Digital Decoder Built-in Speaker System HTS-5010 This item was found at my grandmother's house. Although it is unused, it is a vintage item, so please consider it as-is for the transaction. This is a very rare product. I believe this is a product that you absolutely cannot obtain anymore in an unused condition. The manufacturer is TAPEX (Denkido Co., Ltd.), known for niche audio products. Originally a subsidiary of TDK, this company no longer exists and has been merged and absorbed into TDK Marketing. As it is not a mainstream product, I believe that very few people own it. While there may be better products available with current technology, I am listing this item considering its historical value. For collectors who will cherish it, how about it? Thank you very much.
