50w Power Amplifier Circuit Diagram. This is the circuit diagram of 50w power amplifier based on audio power amplifier ic stk 1050. The amplifier uses a pair of power transistors that are mj2955 and 2n3055 to amplify the input signal.

So easy to builds. This simple 50w electronic amplifier circuit diagram project is an ic amplifier module from st microelectronics the tda7294. If you want to get more out of it you will need to put another pair of the output transistors in parallel increase the power supply rails and increase the gain of the power amp by lowering the value of r14.

It is intended for use as a top quality audio class ab amplifier in hi fi applications.

Besides the price is relatively affordable the sound quality was arguably tolerable for audio lovers. You must use a heatsink on those transistors. You can choose 0 5w to 1 200w. Tda7388 4 50w audio power amplifier original circuit diagram tda 7388 easy and more powerful audio amplifier.
