There is 240v going into the transformer and 9v 1 A coming out. i want to replace the transformer with a 9v battery so i can run this device from batteries rather than from the mains. Thanks guys!

I have taken apart a speaker set which uses a transformer to transform the 230-240v mains it receives into 9v AC 1A. I want to connect this circuit to a 9v battery. Nothing complicated-the standard Duracell one. Does anyone have any advice/comments on whether this will work or not? Regards...
