I had a AIWA DX-`100-MU that died. I could not find anyone to repair it. I scearched the internet and found Pioneer PD-F1009 301 CD DISC FILE CHANGER. What a neat product. The AIWA came with a note book that had pockets for each CD 1 to 100 I was lucky to remover all my CD in order and install them into the Pioneer. I connected it to my BOSE and now I am in hog heaven. Now all my CD'S are protected and I can listen to my music for hours. WAY TO GO...
