Check out the Yiroshi power amplifier project where I created a separate PCB driver with the final transistor. You can view the PCB Layout in the images above. This power amplifier delivers excellent performance. You have the option to enhance it further by adding additional final transistors for increased power, current, and voltage. Just make sure to balance it out with a larger power supply current and voltage. For a more in-depth look, watch the full video below:
