Amplifier Classes Basic Car Audio Electronics Amplifiers Class of Operation. Most mobile amplifiers use complementary transistor pairs to drive the speakers. In this configuration there is a transistor (or group of transistors) which conducts current from the positive power supply voltage for the positive half of the audio waveform and a different transistor (or group of transistors) which conducts current from the negative power supply ... Power Amplifier 2000 Watt Schematic Design This is linear power amplifier 2000 Watt which need advance knowledge in electronics since the schematic diagram is very complex for hand made circuit.I think you have to re design the schematic diagram using circuit diagram software designer such as diptrace, eagle, expresspcb ect. Class B Power Amplifiers Learn About Electronics The circuit in Fig 5.3.2 shows how class B bias can be used in a radio frequency (RF) output stage. Although the circuit would produce severe distortion as only half of the signal wave form produces a current in the load, because the load in this case is a tuned circuit resonating at the signal frequency, the resonating effect of the tuned circuit ‘fills in’ the missing half cycles.
