Hi there! I always wanted to build a class a amplifier but don´t want it too complicate. I thought about a good opamp followed by transistors,fets working in class a and am still looking for a schematic. Anyone seen and tried such a thing (maybe some links etc.)? A regulated power supply...

Hi there! I wanna try another headphone amplifier and have an eye on the cmoy cause it´s so simple. Because I have found a little case with jacks for in and out I wanna make a PCB design to use those jacks and solder them directly on the board. I once tried to do it with a LM386 and it was a...

Hi there! I wanna built a solid amplifier with the LM3886. It´s obvious I need a well dimensioned PS but for what reason should I take one transformer for each channel? I often read about this but really don´t see the point. And what´s going on if the voltages of the transformers are...
