Hello,
I have a Logitech 2.1 Speaker System, it has obviously 2 speakers and 1 subwoofer. I also have a home theater with 2 speakers and 1 subwoofer, but it is not working.
My goal is to build another amplifier to use with these speakers + subwoofer of the home theater. I am thinking in cloning the Logitech project. I have opened the amplifier and it looks like simple to build. I have found so far the components:
2x 2200uF
8x 100uF
4x 220uF
1x 47uF (did I read wrong? should it be 470uF?)
1x BT2025BH (here is our problem)
All capacitors are eletrolytic 16V.
I have another CI that has a heat sink, I will have to use the solder to remove and see the CI model.
But, this BT2025BH, I cannot find the datasheet anywhere. I put in google and a lot of chinese and korean websites are shown. I read in a link that it could be replaced by KA2026 or TEA2025B.
Does anyone know a CI replacement for this BT2025BH?
Sorry if I'm telling something wrong, I'm not an expert in electronics.
Thank you all for the help
