Fig. 1.3. Differential Amplifiers. We tried differential amps. to test and see their characteristics. We are unable at this point to invest in purchasing MOSFETS. So we are using BJT’s as replacements until we get some MOSFET’s.

4-b. We then tried different Class AB amplifiers. We tried class AB setup because we can push more voltage and current from this kind of setup. It is because two transistors are used. Each transistor only excerpts about 70% or work. Thus, this keeps the heat of the transistors down and solves the zero cross over distortion as seen in Class B cases.
