STEREO AUDIO AMPLIFIERDate Started: July 14, 2015 Date Finished: July 15, 2015I. Objectives1. To be able to create a POWER STEREO AUDIO AMPLIFIER.2. To be able to learn how to read the schematic diagram3. To be able to solder4. To be able on how to put the components in their proper places on the PCB board.5. To be able to learn how to read the symbol or color codes of the resistor

II. Procedures / Steps in Assembling Project

1. Get all the components needed2. Review the Schematic Diagram3. Check if the components are complete and correct4. Check if the components are functioning well5. In soldering the components make sure not to make contact the components w/c have different foil pattern, if so it will be shorted.6. Get the resistors resistance value7. Solder all the resistors in the right place8. Solder all the diodes in the right place9. Find the Base, Collector and Emitter of the transistor10. Solder all the transistors in the right place11. Solder all the polarized and non-polarized capacitors12. Solder the Integrated Circuit (IC) together with the heat sink13. Solder the eyelet terminals in the right place14. Solder all the potentiometers in the right place15. Solder the wirings in the eyelet terminals16. Check again all the components if they still have resistance or continuity and lastly the wirings.
