The Cmoy Headphone Amplifier Component Parts 2

A Picture say a thousand words, As stated very clearly that what are the component needed for this Cmoy amplifier. Print and bring this out with you when you go to the radio shack to get this component.



Assembly The Cmoy Headphone Amplifier

Step 1
Get ready your PCB Board.




Step 2
Mark out the center ground.





Step 3
Solder the battery clip wire on to the PCB board as shown above.





Step 4
Solder the Power Led onto the board as shown above.
Add R6 Resistor 10k Ohm as shown above.



Step 5
As you can see on the picture above, the green line indicate that we have to solder and connect hole 4 to 5 to 6. On the other side we have to solder hole 9 to 10 to 11.
____________________________________
*NOTE: How to solder the green line?
There are 2 type of joining the green line, for beginner I will suggest you to use type "A".
Type "B" need more stable hand but less of trouble to cut the left over wire from resistor or capacitor.
___________________________


Once you have done up to step 5, you should test your circuit by connect it to a 9v battery and toggle on the switch, the led should be lighted up. If you can't get the led to work, please go back to STEP 4, Reverse your Power Led connection and test again.
