This is a build I did of a LM3875.  Really easy chip to build, only thing i don't love about this chip is that it is only really stable with an 8 ohm load, anything else and it protects itself by limiting power output.

It's a really clean and crisp sounding chip amp, I'm actually pretty impressed with the sound quality.
Next I plan to  build a 4 channel amp using these chips, and build a 12V to 35V DC converter so i can use it in the car. Should be a cool project, I've just gotta wait till the funds come in.


Anyways, on the the pictures :)
