This device came to my shop with no power, no stand by power, and nothing comes on the screen of this CD player. It was completely dead. When I examined the CD player from the outside, I found a 110/220 switch and the switch was pushed to the 110 side and in our country, the voltage is 220. So what happened was, they have plugged 110 volts CD player into a 220 Volts power line. And the result was a dead CD player.
Audio Restoration Repair Project: Bose Wave FM AM Radio Receiver, and conversion from 110-120VAC to 220-240VAC
This particular version, manufactured in 1994, is a very well-made unit, capable of long-life, with satisfying sound.
The internal components are of high quality from reputable manufacturers, which is a pleasure to see. There was only one capacitor which was out-of-spec – very rare to see in a 15-year-old unit.
