LIL' BUDDY AUDIO POWER AMPLIFIER

I had seen recent efforts to use 2N3904 and 2N3906 transistors to make an audio power amplifier. This is my take on this exercise.

The LIL’ BUDDY AUDIO POWER AMPLIFIER is a high performance amplifier intended for around 10W output power. The design is 100% transistor based, using the ubiquitous MMBT3904 NPN and MMBT3906 PNP types exclusively, including the power output stage. The PCB design is optimized for automated pick and place SMD on the primary side with 6 hand soldered THT components on the other side.
