Bose wave radio:one or more stuck discs

Followed instruction in Part 2. No problems until I tried to get the disc out. It would not budge even when using small pliers! Thought What now? So I plugged the power cord in. CD tray came to life, and I was able to remove the disc.. Reassembled the Bose, and tried another CD(original ruined). Played, and ejected faultlessly.
