ETB-070 – Two Stage Transformer Coupled Amplifier with Power Supply is an educational trainer designed to study the construction and performance of a two-stage transistor amplifier using transformer coupling. This setup helps demonstrate how transformer coupling affects voltage gain, impedance matching, and frequency response. Ideal for analog electronics laboratories, this trainer allows students to measure stage-wise and overall gain, and observe the role of transformers in multistage amplifier circuits. It includes a built-in regulated power supply and test points for oscilloscope or multimeter connections.
