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