Just pulled the trigger on a slightly beat-up AIWA 990! I've been keeping an eye out for one of these beasts for years and watching the value keep going up and up and up. While it has been well used for the past 35 years, it still sounds great. This one-owner unit was bought in 1982 while the young man was in college. He wanted the best sound for his dorm and ended up with this unit. While he said the original receipt was included, I don't see it but he said he paid around $385.00 USD. He mention he also had the books with it and he produced the owner's manual, a spec sheet, the warranty card and even a demonstration cassette. I've never seen an AIWA Demonstration Cassette and imagine they are fairly rare. This came with the cord but he also mentioned a 12v wall wart plug that it didn't have. I though it was kind of odd to have both types of power but maybe somewhere in the world 12v is desirable.
