Hello all,

I have an old TV and I decided to salvage parts from it. I decided I would rebuild the audio amp on it to be used separately in a custom PC monitor case I'm building, but I can't for the life of me make sense of the circuit diagram.

I do not understand how the components would physically connect since the only diagrams I could find are disjointed.

The Chip I salvaged is kind of crap, but it's an an7522. here's the two best diagrams I have. The second one is a modified Russian schematic I found to be a little more fleshed out.

I could use just some advice on reading this type of diagram (not sure if it's properly called a block diagram), or just a redrawn schematic I could make sense of. I just don't see how these connections make sense.
