ETB-130 – Study of Complementary-Symmetry Transistor Power Amplifier with Power Supply is a specialized trainer designed to demonstrate the working of a Class B complementary-symmetry transistor power amplifier, commonly used in audio amplification due to its efficiency and low distortion. This model helps students understand the principle of push-pull amplifier configuration using complementary NPN and PNP transistors. It facilitates experiments related to input/output waveform analysis, crossover distortion, power efficiency, and heat dissipation characteristics of transistor power amplifiers. The built-in power supply and test points make it easy to analyze voltage gain, waveform symmetry, and overall behavior of the amplifier stage under different signal conditions. Key Features:
