Hi,
I opened up my pc speakers and they contained a tda2007a chipamp.
The ST internal schematic is making my head hurt !
What type of input stage is on the tda2007a ?

DJ Exprice said:Explain what you are using as a schematic for the real amp. I might be able to tell you if you are going to need to fret the internals or not. Don't worry for now.
PS: I think I might build one of these
Hi,
The chip was inside my active pc speakers powered by a 12V dc supply. Looked to me like a standard datasheet implementation. The potentiometer was failing after four years putting dc onto the left speaker (which is now failing) and throwing the balance way off.
After searching the forum I think the chip has a single common-emitter input stage.
Here are the speakers. Can't do that with a flatscreen!
