How do I make a 50W amplifier using BJT's? We need to use 24V source. For some reason, we weren't able to make it work. without the load resistor (which is supposed to be a 4 ohm speaker), the circuit amplifies from 300mV to approximately 5V. What can I do to make it work? Or is there a good design I can follow?
Specifications: 24V, 50+W, Using BJT transistor, resistors, and capacitors. (No Op-Amp) 4 ohm speaker for the output, the frequency response can be any good range for mp3 songs. Minimized noise and distortion.
