HIFI Stereo Class A Power Amplifier Board Audio Amp Module High Quality DIY Kit

About this deal

This is a stereo Class A power amplifier board available as either a pre-assembled module or a DIY kit for self-soldering. Class A amplifiers are distinct in that their output transistors remain conducting at all times , which eliminates the crossover distortion that affects Class B and AB designs. In a Class A output stage there are no abrupt nonlinearities and no turn-on or turn-off delays, and the smooth transfer characteristic yields low-order harmonic distortion that can become unmeasurable at low power levels. The listing covers two amplifier boards, available as either assembled units or DIY kits. Class A designs run hot, so adequate heatsinking is essential , and a suitable external power supply and enclosure will also be required to complete the build. This makes it a rewarding project for audio enthusiasts who are comfortable with soldering and basic electronics assembly, and who want to experience the warm, low-distortion character that Class A topology is prized for.
