In this post I make a 500 watt stereo amplifier board using 2SC5200 & 2SA1943 transistor. This amplifier can deliver 500 watts RMS at 4Ω. For power supply you can use 45-0-45 to 50-0-50 volt 10 Amp 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.
When your amplifier is ready please test series lamp after input direct power


*Series light test..........Connect a 30-100w lamp with transformer's 220v ac line in series.

* Now test this amplifier.

1. Speaker output voltage.....0.00

2. Biasing voltage........0.4-0.7

3. Audio input voltage.......0.00

4. 2SC5200 collector voltage.........[+] positive volt.

4. 2SA1943 collector voltage.........[-] negative volt.

6. 2SC5200 & 2SA1943 base voltage.........0.1-0.2

7. 2SC5200 & 2SA1943 emitter voltage.........0.00
