Hello! I apologize for my boldness, but I can't solve a situation. I have a CD player Sansui cd-a717DEXTRA whose optical drive has started to fail. I read a post in which someone said that you live in Japan. I am in Europe. I would like to know if there is a possibility to identify in Japan a source for the purchase of such a part, original optical unit KS 152A. Thank you very much! Have a peaceful day!
