Radio, electronics, computing, telecnology. Donations are gratefully accepted and always go towards improving the site. 3W RMS Stereo Amplifier Is Very Small. I recently came across these little 3W class-D amplifier modules that had sprung up all over eBay. At $1 a piece delivered, I figured that there was little to lose in ordering one and testing it out. At 05W. Efficiency of 83% when driving 4 ohms, and 87% for 8 ohms. The high efficiency comes about from the so-called class-D operation of the amplifi...
