Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
The manual was very helpfull, it answerdes all my questions, and i was surprized to find the original manual on this site! Big thumbs uP:)
