Yes, a little more information would allow us to help you! 😉

Do you mean that you are looking for a kit that uses discrete components? If so then the Autocostruire (Audiodigit) 2020 amplifier may be just what you are looking for!

im looking for just a schematic with individual transistors and such, not a circuit based off of a big chip like one from tripath

please 😀

Check this design... http://hem.passagen.se/johanps/

The first version, 0.5 is a low power version, running on +- 5 volt. My guess is, that you can turn up the supply to 10 volt with a few ajustments.
See: http://hem.passagen.se/johanps/Amp0_5/Amp0_5.pdf

thank you very much, that is exactly what I am looking for in a relatively simple layout

thanks, and if anyone else has something similar, please post it as well

Hi,

I could recommend one to you but what are you goals, why only ten watts, does it just have to work? Basically is this a project for school or....?

Might have a real hard time getting something to "just work" it takes alot of effort, have a look here:

yup its a project for school

this is just to see if the project will be worthwile and i guessed the lower power ones would be more simple

and thanks for the link

See my blog
there's actual a 10 watt one in the photos, K1410 version 1.1.
simple and suitable for school training purposes

Kenshin: could you give me a link to the schematic please, its hard to find b/c i cant read your site...

EDIT: Oops, goes to show you I don't know what a class D circuit looks like .

There are two schematics and two pictures of a completed unit found here....
