2sc5200 2sa1943 audio amplifier produces a high power output the output watts is around 200 at 4 ohms load of impedance. Construction of a class a amplifier. In building a harmonious and beautiful life tube amps have become a saved by eric greaves 60.
The use of transformer permits the impedance matching resulting in the transference of maximum power to the load e g.
Power amplifier circuits output stages are classified as a b ab and c for linear designs and class d and e for switching designs. The classes are based on the proportion of each input cycle conduction angle during which an amplifying device passes current. Class c amplifier is tuned amplifier which works in two different operating modes tuned or untuned. Circuit diagram of typical single stage class a amplifier is shown in the circuit diagram below.
