Since the debut of those two Cambridge models, however, the need for iPod integration has become an even more critical feature for lifestyle-friendly audio products. Two of our favorites were from Cambridge SoundWorks-the company's Radio 730 (Read review ) and Radio CD 740 ( Read review )delivered some of the best sound quality we'd heard from a tabletop radio. In past few years, however, the market has been crowded with competitors including Tivoli Audio, Polk Audio, and Boston Acoustics, not to mention upstarts such as Chestnut Hill Sound. To remove the 4 screws holding the display board on use a small needle nose pliers to grip the plastic standoffs and then remove the screws (noting the position of the one with the insulation washer).ДЄt this point I am stopping until the LED's I need arrive.( ) - The realm of high-end tabletop radios once seemed to be the sole domain of Bose.

I used a Hakko FR-300 desoldering iron, be careful, removing the display board as I broke one of the pads (white arrow below) on the under side of the board (although it did not go anywhere). Left (positive is top negative is bottom) Right (Positive is bottom negative is Top). Also note that the polarity of the 2 connectors on the right is the opposite of the ones on the left. Desolder the connections (white arrows) noting the polarity of the 2 wires on the left. I decided to remove the display board from the main circuit board, it seems easier to work on that way. The control panel circuit board should come out of the front panel. Gently pull the round knob in the center of the control panel off and remove the nut from the POT/Encoder.

To remove the control panel circuit board remove the 4 screws (yellow arrows below). I removed all the connectors and the circuit board from the back panel (blue arrows) there are more connectors on the top.Д¬arefully remove the hot glue (green arrows) as you will need to feed the speaker cables through their holes so you can access the back of the front panel. Now place a unique mark on the connectors or take pictures to make sure you can reconnect the connections on the back of the unit later. There is a piezo speaker on the bottom of the unit, mine popped out of it's holder. There are two screws holding the CD player to the faceplate (yellow arrows below). Once the top cover is off, you'll see the CD player. There is a connector for the snooze/mute button that I disconnected to make it easier once the cover was open.ДЁ. You'll have to pry away at this one a bit, but it wasn't too hard. At this point, you'll need to remove the top cover. Once you've removed that, you'll need to then remove the 6 screws (Red arrows) from the 'sub bottom'Д¦.

Note: you'll need to remove all the foot-pads as well (there is a screw under each).ДҐ. Remove the screws from the bottom, and remove that base. Flip the unit over (so the bottom is up). You'll need to remove those, and separate the back from the unit (this will be easier when the bottom and top are removed).Д¤. On the back of the unit, there are 4 more recessed screws. There are 4 screws on each side (not the speaker screws, the recessed screws). I'll take the Bose! Not all of the steps below are needed to work on the display but I am going to give this unit the once over since it was rather dirty, and since it is open and a pain to work on I don't want to go back in to it.Дў. Let me say that given a Bose or a Cambridge to work on. I recently picked up the aforementioned radio only to find out that it has a dead back light on the display.ДЇirst thing was to open the unit.
