Push Pull Amplifier with power supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12134
Indian Lab Suppliers supplies the Push Pull Amplifier with power supply (Product ID: 12134) as part of its electronics engineering lab equipment range. It is a training board for studying a transformer-coupled class B transistor push-pull amplifier at audio frequencies.
Quick Answer
The circuit uses three PNP transistors with a driver transformer and an output transformer, and a band switch selects one of four output loads. Students measure output power, plot the frequency response and measure distortion. In class B each output transistor conducts for half of the cycle, so the effect of crossover distortion at low signal levels can be observed. Power comes from a built-in IC-regulated −9 V DC, 50 mA supply.
