This slim little board has a class D amplifier onboard that can drive 2 Click-and-Pop Suppression; Short-Circuit and Thermal-Overload Lab Gruppen Lab500 Power Amp in Musical Instruments & Gear, Pro Audio Equipment, INSTRUMENTS LM386N 4/NOPB IC, AUDIO POWER AMP, CLASS AB, 1W GE 286 NPN Silicon RF Power Transistor Large Signal Power Amp 15W DIY Kit 8X2200UF 35V Sanyo Capacitor Array Power Amp Filter Circuit Board As we said above, the Class AB Amplifier is a combination of Classes A and B in that for small power outputs the amplifier operates as a class A amplifier but changes to a class B amplifier for larger current outputs. This action is achieved by pre-biasing the two transistors in the amplifiers output stage. Discrete Class AB Transistor Audio Power Amplifier Circuit Diagram This is a class AB transistor power amplifier. It is a simple amplifier to build, uses standard parts and is stable and reliable. The entire circuit utilizes commonly available components and may be simply built over a general-purpose board. The modified circuit now is known as Class AB amplifier circuit.
