Thank you very much for viewing. This is a slow-speed 8-track tape. One channel contains one-way broadcasting. The audio source is from the Sakado area. I am listing this for sale to organize my collection. I performed a light playback check when I obtained it, but I do not guarantee its current functionality. I cannot accept returns or refunds if it cannot be played or if there are issues with the sound quality. There are scratches and stains. Please refrain from purchasing if you are looking for a pristine item or are overly concerned about condition. Please understand that this is a used/surplus item before purchasing. Also, please refrain from excessive price negotiations. Shipping will be via Rakuraku Mercari. Shipping may be delayed due to work commitments. Thank you for your understanding. Please let me know if you have any other questions. If you wish to purchase multiple items currently listed, please let me know. A discount of around the shipping cost is possible. However, I cannot negotiate based on a specified amount. Thank you for your consideration.
