STEREO AUDIO AMPLIFIERDate Started: July 14, 2015 Date Finished: July 15, 20151. Objectives1. To learn more about amplifier 1. To learn how to solder1. To be able on how to put the components in their proper places on the PCB board.1. To be able to learn how to read the symbol or color codes of the resistor1. To be able to learn how to read the schematic diagram

1. Procedures / Steps in Assembling Project

1. Get all the components needed1. Review the Schematic Diagram1. Check if the components are complete and correct1. Check if the components are functioning well1. In soldering the components make sure not to make contact the components w/c have different foil pattern, if so it will be shorted.1. Get the resistors resistance value1. Solder all the resistors in the right place1. Solder all the diodes in the right place1. Find the Base, Collector and Emitter of the transistor1. Solder all the transistors in the right place1. Solder all the polarized and non-polarized capacitors1. Solder the Integrated Circuit (IC) together with the heat sink1. Solder the eyelet terminals in the right place1. Solder all the potentiometers in the right place1. Solder the wirings in the eyelet terminals1. Check again all the components if they still have resistance or continuity and lastly the wirings.
