The board represents an extremely useful tool for studying the power amplifier of A class and B class.

In fact, it provides 4 amplification architectures among the most common in preamplifiers (A class) and final amplifiers (B class), with the possibility of analyzing the power stage and/or the drivers.

The board is designed to afford the problems connected to the introduction of negative feedback into an amplifier, and to its influence on the different parameters: amplification, bandwidth, input and output resistances, noise.

The board provides a full support concerning the elementary amplification configurations.

It affords the problems related to the use of FETs and MOSFETs in the three basic configurations: common source, gate and drain.

The board analyzes the components normally used in cascade to transformer and filter to realize stabilized power supply units with bipolar technology.
