In this post I make a 200 Watts R.M.S amplifier using 2SC5200 & 2SA1943 Transistor. Which can deliver upto 100 Watts in R.M.S power at 8Ω per channel. We test this amplifier, and we got it's frequency range 30hz-20khz. For power supply you can use 30-0-30V 5A 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.
After complete this board don't forget to series light test. After connecting the series light, make sure that the series light does not turn on. If the series light not turn on, then check the voltages.
Speaker output voltage = 0.0 volt
Baising voltage = -0.5 to -0.7 volt
Audio input voltage = 0.0 volt.
If you get same voltages, then connect preamplifier to input and connect speaker to output.

    Hi, I made this circuit, everything is great, but in some frequencies, such as piano sound, it makes noise (hissing sound), of course, I used a 24-volt, 3-amp transformer for testing. Could the problem be with the transformer?
