Class A Amplifier Circuit Diagram. Let s talk about the input voltage of the power amplifier is a 30 volt dual power supply at 5 amperes of current. This is completely portable.
Class a power amplifier circuit. Let s talk about the input voltage of the power amplifier is a 30 volt dual power supply at 5 amperes of current. The circuit consists of a preamplifier ic which will amplify the input audio signal.
The circuit diagram of a two stage single ended class a power amplifier is shown above.
Usually the load is connected through an output transformer because it provides the perfect impedance matching. From the above figure it can be observed that the transformer is present at the collector as a load. The following figure shows the circuit diagram for class a power amplifier. The use of transformer permits the impedance matching resulting in the transference of maximum power to the load e g.
