Now I am designing an audio amplifire This is the whole image of a channel of it. Please see linked circuts for details.
CONCEPT
2 channel stero system.
Good sound using less expensive parts.
Enough, but not too much output, good power efficiency.
FUTURE
Multiple inputs selectable balanced or unbalanced, and mixing them up for output.
Work as balanced processing system internally.
