Discrete Transistor Class AB Amplifier Audio Test!

It’s time to push the limits of our custom class AB analog amplifier board! Let’s push the NPN and PNP transistors near their limits by listening to some music while monitoring the waveforms on the oscilloscope!

Let’s meet at the electronics workbench to test our prototype class AB amplifier!
