sorry buddy, they are not complete schematics.
Just tutorials on output stages.

Ok, 30-50W is a nice number, but...
50W per channel or total?
How many channels?
50W for what load impedance - 2, 4, 6, 8, 16 ohms?

Answer ALL those questions, then it is possible to talk about the actual design.

Hello,

Here is a page from the EDUCYPEDIA on amplifier classes:
http://www.educypedia.be/electronics...ierclasses.htm

There are more pages like that on audio subjects:
Audio: Amplifiers Audio compression techniques Digital audio General overview Amplifier classes Audio file formats DSP Midi MP3
