Now, let's compare that schematic to the ubiquitous 741 (not designed by Widlar)
Notice any difference? Of course you do they are very different designs - and yes they had very different specs as well - but the point is these seemingly simple building blocks were internally very, very different and they sounded different.
Here is a schematic of a modern day favorite for audio designers and found in many designs, the NE5532. Notice also that as time goes on in the progression of designs the number of components increases? Just look at the amount of parts in the 709 compared to the 5532.
OK, so tomorrow, let's show you how all these complicated looking schematics can be easily understood and broken down into simple terms. I think you'll find tomorrow's post interesting and easy.
