Solder DC in directly to the connector board of Bose Soundlink 1?

HI,

I bought a Sounddock 1 Series and the Power adapter is dead. Those Adapter are expansive, and rather buying one I have a DC with same voltage +18V with 1A.

However the bos has a 4 pins connector.

Which one is positive and which one is neutral?

I have no way to test it.

Does my DC is suitable for this?

I know Bose power supply is +/- 18V 1A

Please let me know if you can help!

Many thanks

Tony, the connector is a 4 prong Molex 5.5mm square Size 5.5 x 5.5 x 6.4 mm (each four pins are separated)

Pin1 = +ve 18vdc

Pin2 = -ve 18vdc

Pin3 = GND

Pin4 = GND

As for suitability of your adapter, it depends on what you have and what the outputs are. Use a multimeter and see what you get.

So the adapter shouldn't be used as only provide +18V right?

so +18Vm shouldn't do the job...?

That is correct. You will need to come up with -ve 18V as well as +ve You could use a DC-DC converter, but by the time you added the cost for that, it may be cheaper, and easier, to use an original Bose power brick.

For anyone looking for a replacement, looks to be a Molex Micro-Fit 3.0™ Receptacle Housing, they've even got a video and a range of overmolded cable assemblies!
