What I am about to say is to help you. Not to offend you in anyway.
If at this point you have no basic idea about an amplifier - talagang malabo - it is not recommended to build one. You will waste your money, time and you will learn nothing. There are 2 sides of the coin here. Your professor is not a good teacher or you need to work harder as a student. I suggest you determine which side is the problem then do something about it.
If you noticed, nobody has replied to your post for quite some time now. It is because it is not easy to help somebody on a relatively advanced subject when that somebody do not have the basics. Once you have the basics, many people in this forum can help you. I hope you understand this.
