looking for some open sourced schematics for some audio amps that I could make without ordering a kit. I may need some help fully understanding the schematics aswell, although i do have quite a bit of knowledge about electronics and electrical theory. Any help would be greatly appreciated. I want these audio amps for big projects (DIY stereo's) and small projects(portables).

Dunno bout any big DIY amps, but I do know if you just google LM386 (or any similar small amp), you'll find bunches of schematics for it floating around.

k thanks dude, Ill check er out.

The Texas Instruments tpa6021a4 chip is an excellent 2w stereo amp with headphone jack support. I used it in 2 of my laptops and it works great! I also have a couple PCBs with digital volume control for sale if you're interested....

cMoys Amplifiers are a great way to learn about the basics of amplifiers

There is an excellent guide here on protoboard

heres a Freeform version i just finished with no PCB its nearly like your looking at the schematic:)

As you can see it is a simple layout
