Question about Boston Acoustics BA65 Computer Speakers
Model # BA265 powered two-piece speaker system. I tried to swap in other AC DC 12V cords from my other household electronics, they all look like they would fit but non of them do. I think maybe that's because A: the power supply has a unique 12V adapter, or B: the power port on the back of my speakers has become damaged or displaced from its original postion; but of course I'm not sure can someone please help?
Not only do you need the correct voltage and amperage (MAH) but you need the corectly sized plug to fit the socket AND it has to be in the correct polarity. Usually the polarity is marked by a broken circle with a dot in the middle. Leading to this dot will be an arrow or just a line and at the other end of the line will be either A positive (+) or negative(-) It's important you get this polarity correct when plugging a new power supply in.
Your local electrical store should be able to sell you either a fixed 12volt supply or even a variable supply allowing 3, 6, 9 or 13 volts output. Make sure it has the amperage capacity you need. It won't matter if you need 500Mah and the supply is 750Mah as long as it isn't less than what you need.
The power supply should come with an assortment of plugs which are insrted into the socket on the end of the power supplies lead. Follow the instructions on the packaging and ensure you have the center pin set as either + or -. If you are in doubt. Take your speaker which has the socket fitted and show the salesman. He should be able to pick the correct plug and make sure it's the right way around.
If you plug it in and nothing lights up, quickly remove the plug and turn it 180 degrees in the power lead socket. Obviously it's been put in the wrong way round. If you were quick enough no damage should have occured and away you go.
Just one tip. Wrap a small piece of insulation tape around the plug to stop it from being pulled out of the power lead's socket. They do tend to work loose after a while. Oh and make sure it's switched to 12 volts if you get the variable one.
