Ben from West Lafayette, IN, wrote in to share his amp project.

A Class-D amplifier operates the output transistors as switches instead of as variable resistors, as in more traditional amplifiers. In doing so, nearly all conduction losses in the output power devices are eliminated, leading to a very efficient amplifier.

My interests include writing, electronics, RPGs, scifi, hackers & hackerspaces, 3D printing, building sets & toys. @johnbaichtal
