Amplifier

Two of my friends, Lynnette, Hwee Har and I did an amplifier for our second year mini project. Each of us did our own parts and cascaded eventually to form the final product. Lynnette did the power supply, Hwee Har the pre-amplifier and me the power amplifier. The specifications given are:

Power:	10W
Voltage:	15V dc
Load:	4 ohms
Equalisers:	Min. 2 band
Inputs:	CD, tape, radio, microphone
Biasing mode:	Transistor biasing
Extra features:	- Stereo with left/right balancing - Karaoke mixing - Short circuit protection

It was a tideous and time-consuming project in addition to the heavy curriculum, but it certainly gave us a great sense of satisfaction after its completion.
