100+100 watt stereo amplifier pcb layout
In this post I make a 200 Watts stereo amplifier. Which can deliver upto 100 watt per channel. For power supply you can use 30-0-30 Volt 5 Ampere Transformer. Now follow my steps for this amplifier. First we make pcb. For make pcb you need pcb layout. download the pcb layout and print it by laser printer on photo paper. Then cut the pcb layout. Then press the pcb layout by iron on copper clad board. Press the iron 10-15 munites. Then leave the pcb for cool down 10 munites. when the pcb was cool, put the pcb in water and move the pcb layout to copper clad board. Then put the pcb in ferric chloride [FeCl3+H2O] for etching 10-15 munites. when etching was end, clean the pcb by water. Then make hole on pcb. And then press the upper side print of pcb. Now your pcb is ready mount components by instruction.
Thank you,
