KLH DA1602 5-Disc CD Changer

This 5disk CD changer has been plagued from the beginning with malfunctions: 1) The unit sometimes presents the slot associated with the currently playing CD as an empty slot. I you don't notice and insert a CD, the unit becomes jammed and needs to be disassembled (cover removed). 2) The unit takes a very long time to go through it power-up sequence. 3) Sometimes the CD tray won't open. You have to then remove the cover and manually open the unit. 4) Switching from on CD to another is very slow.
