➢Step descriptions:
✦Step 1:-Like always,we have printed the circuit on photo paper, and press it with iron.


✦Step 2:-Put it into the water and rub it softly, after this submerge it into ferric chloride, and shake it slowly around 15 to 50 mins.


✦Step 3:-This process will be completed, after this, we will wash it with water. We will remove the print with help of thinner.


✦Step 4:-Now make some holes.


✦Step 5:-After making the holes we will stick another print on the top, and remove it.


✦Step 6:-For better viewing, we can apply vegetable oil on it. And the PCB is ready.

✦Step 7:-Let’s start the mounting. First of all 2 resistance.


✦Step 8:-Solder and install all these parts below on the board:
1 AUX Socket 3.5mm
5 Capacitor 100uF 
1 Capacitor 2200uf25v 
3 Capacitor 470uf 
2 Capacitor 0.001uF 102 
4 Capacitor 0.1uF 104 
3 Connector - Screw Terminal 2 Pin (5mm pitch)
1 Connector 2 Pin (2.54mm) 
1 Connector 3 Pin (2.54mm) 
4 Diode 4007 
1 IC CD6283 
1 Potentiometer- Dual 47K 
1 Regulator IC 7805 
1 Resistor 1/2 Watt 2.2 OHM 
2 Resistors 1/4 Watt 150 OHM 
2 Resistors 1/4 Watt 2.2 OHM 
2 Resistors 1/4 Watt 22K 
1 Resistors 1/4 Watt 560 OHM 


✦Step 9:-Cutting the pins.


✦Step 10:-Before soldering we will apply liquid flux, then soldering.


✦Step 11:-.Attach a knob and a heatsink on ic.


✦Step 12:-Prepare a 12v 1amp transformer,connect it.


✦Step 13:-.Prepare 2 speaker boxes and connect.


✦Step 14:-This is our cable for connecting the phone through the aux connector, let’s connect the phone.


✦Step 15:-Play.
