Default Schematic for audio amps

This question has probably been on this board many times. But I'm looking for a source with good audio schematics. I have found some schematics with pcb layout's and would love to find more like that example. Pages that I've found is
Index of /Audio/Circuits/Power Amplifiers-Linear


but many of them are old. of course there are kits on ebay but I would like to do from the ground up I have done Gain clone but now I am looking for a little more powerful. so I may have to my active crossovers for my speaker project


So any tips are very welcome

happy amature from sweden

This can be a bit of a minefield as some published circuits simply dont work or dont work well.

I would go for one of the common recommended designs on DIYAUDIO.
It will save a lot of heartache in the long run.
