[QUOTE="tekbench, post: 1390335, member: 246450"] [b]Airport extreme cord connector repair - Thanks![/b] Our dog chewed the cord of our AEBS, right at the DC connector end. This makes repairing the cable impossible. Only option was to replace the connector on the end. Went to the Shack, bought a 3$ bag of size 'L' DC cord ends and soldered one on. Works like a champ. Sure beats turning the power supply into a $20 dog chew toy... again. Notes: The white DC supply cable on the AEBS Power Supply output barely fits through the plastic cap on the new solder connector. It will not easily accommodate shrink wrap tubing without reaming the cap out a bit. The solder connectors tend to melt above 700 degrees F, so watch your soldering iron temp. The tabs are small and thin, so don't over-do it with the solder. There is not much room to maneuver around in there. CENTER HOLE of the cord connector is + voltage. The outer portion of the connector is - voltage. On the cable, the CENTER CONDUCTOR is + voltage, while the shield wrapped outer portion of the cable is - voltage from the AEBS power supply. Use a multi-meter to be certain you solder the polarity correctly. The connector is a little bit long. Some of the - DC outer portion of the size 'L' connector shows out the back of the AEBS. It doesn't seem to have any effect on the status of the unit. It just doesn't fit as neatly as the OEM connector. Other than that, kudos for finding the size. They come in 2 packs, so keep the second one handy for the next time the dog chews it off. The Barrel size is: 5.0mm OD x 2.5mm ID in the event you want to buy a pile of these from digikey or some other parts supplier. Radio Shack part number I show is 274-1568. Description reads: "Coax-style in-line DC power plug" Thanks again for the lead on the cord end size. - Tekbench [/QUOTE]
