How to make pcb by ironing method►
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 minutes. Then leave the pcb for cool down 10 minutes. 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 minutes. 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.

How to test this amplifier►
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.

First check driver stage. Connect the black probe of multimeter on Ground, and red probe on TIP42C collector, you get - volt (-47). And on TIP41C collector, you get + volt (+47)

Then check Biasing of this amplifier. Biasing voltage - 0.5 to 0.7

Then check Speaker Output and Audio Input voltage. Here you get no voltages 0.00V.
If you get same voltages, then connect preamplifier to input and connect speaker to output.

Thank you,

  2. Sir mujhe pcb digram chahiye me blank bredbord pe banaunga isse our sound quality bohut badhia he par me subwoofer kaliye use karna chahata hun

  3. Sir my biasing voltage is about 27volt.output is also same.I use 30-0-30 TRFX. I examine my pcb many times nothing is in wrong way.But series light get blown when I connect my speaker.I also examine my pcb tracing it's perfect.Please help me how to solve this problem.
