This project is addressed to those in need of a high fidelity amplifier for a small or medium space.
In fact it’s simple to build, very compact (78 x 88 mm) and with enough power.
Sound quality can be a very heated and subjective debate.
Here’s a glimpse into the PCBs, top:

The power source is a full-bridge power converter based on a ETD49 core.
*The pulse modulator control circuit is provided by SG3525 and NCP5181 power mosfet drivers without power factor correction.
The SMPS800/1KW also features an advanced over-current protection which limits the output current in case of temporary overload.
