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!  |

| The input stage is a common emitter single transistor amplifier followed by a emitter follower. The equivalent internal circuit diagram seems to have broken the rule that input to output is usually drawn from the left to the right. |
