Power Amplifier Diagram. A 4 ohm speaker or two pieces of 8 ohm speakers in parallel. However the efficiency is low and so is the output impedance.
The amplifiers are classified based on the applied signals either it is the voltage signal or the power signal. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced. Circuit diagram of 150w power amplifier circuit.
The circuit features high power good definition and very low noise.
The use of transformer permits the impedance matching resulting in the transference of maximum power to the load e g. Voltage amplifier circuit and power amplifier circuit. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced. A 4 ohm speaker or two pieces of 8 ohm speakers in parallel.
