My speaker won't work after a power surge that damaged some of its components.Its a creative5.1 sub woofer system.a technician told me that a preamp IC BT9843 is blown and needs replacing.I cannot get it in my country .Help me get an equivalent that can work please.
Try searching again using Google, using BT 9843, but when you look down the results ignore the two letters and see if you can find an IC which is the same numbers, even if it has different letters on the front. Those letters could be just the makers letters, with the device made by different makers.

The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.

Plug the speaker to a known good output from the other components. if it works, then it's your output, if it does the same thing, then it's blown.
