Posted during July 2016 in the old forum: Today I´m glad for two reasons: the first one is that I´ve received a N.O.S fully working walkman and the second one is that is a Philips! my favourite manufacturer This unit was one of the top models in Philips range between 1991 to 1995. It´s far from the Sony or Aiwas top models of that time, but not so far to their medium ranges. It features first class look, with a very well finished surface (although is plastic), Dolby B, bass boost, and the most interesting thing is that reminds me some Aiwas mechanics. I suppose that this unit was developed in collaboration or Licensed by Aiwa ....
