Volume 2 of the Bose Wave Radio Master Repair Manual series takes you inside the three-disc CD changer – the most complex and failure-prone part of the Bose Wave system. Working from a real bench workflow, this book shows every major changer fault I see in the wild: discs that won’t load, “PLEASE WAIT” hang-ups, jammed trays, noisy elevators, and random DISC ERROR messages. Each problem is broken down into a clear symptom → diagnosis → repair sequence, with high-resolution color photos and callouts that show exactly what to look for. You’ll learn the full teardown and reassembly process, safe ways to clean and re-lubricate the mechanism, how to recover from timing mistakes, and how to test the changer on the bench before it goes back into a system. Whether you’re a hobbyist trying to save a favorite Wave radio or a technician adding Bose work to your bench, this volume gives you a step-by-step reference you can keep open next to the changer while you work. This book is designed to sit alongside Volume 1, which covers the main Bose Wave radio, power supply, and control electronics. Together, they form a complete repair and restoration guide for the Bose Wave system.
