Hi, I found my old Sony WM-33 a few feeks ago, and was really excited to have it fixed. Ordered the central gear replacement and installed it successfully. Found my old cassette tapes and bought a pair of Koss PortaPro
Thanks! Turns out my Walkman-fixing-fu wasn't as strong is I thought (see my post in Walkman tech talk http://stereo2go.com/forums/threads/sony-dd-wm-33-sound-quality-issues.2808/)
