Small Audio Power Amplifier Using Op-Amp and Two Transistors
https://www.deeptronic.com/electronic-circuit-design/small-audio-power-amplifier-using-op-amp-and-two-transistors/
Using two small transistors (2N3904 and 2N3906), we can build small power amplifier which deliver several hundreds milliwats. The basic circuit is a totem pole transistor pair with small biasing circuit configuration to give small leakage idle-current. Let’s see the schematic diagram of the circuit in the Figure 2.

possible to make a suitable amplifier using an op-amp and a couple of external power transistors, but we went with a simpler solution, and chose a chip that was specifically designed as an audio driver, the LM386, shown in Figure 1-5. Figure 1-5 – LM386 internal circuit and 8 …
Simple 300 Watt Power Amplifier Circuit using Transistors
https://makingcircuits.com/blog/simple-300-watt-power-amplifier-circuit-using-transistors/
The proposed amplifier circuit uses complementary transistors to achieve the intended high power with Hi-Fi quality. The unit is powered with a 45V + 45V supply, with current not more than 7 amps. Most of the incorporated transistors barring the BC556C must be mounted on the heatsink, which must be prferably fixed over one of the sides of the cabinet to facilitate …
