Hello, I just entered the world of portable cassette players a few weeks ago, after I bought an Aiwa HS-G36 of eBay. I am a big fan of analog media of all kinds especially cassettes and vinyl records. Now that I entered the Walkman-world I just bought another nice unit from eBay: A Sony WM-DD22 and I was blown away by the sound quality of that device compared to the Aiwa. I hope that I can find help and advice especially with repair and service of portable cassette players. Greetings from Germany Nico
