Audio Amplifier (CE) with power supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12132
Indian Lab Suppliers supplies the Audio Amplifier (CE) with power supply (Product ID: 12132) as part of its electronics engineering lab equipment range. It is a training board for measuring the gain, bandwidth and impedances of a single-stage common-emitter transistor audio amplifier.
Quick Answer
The board carries a common-emitter amplifier built round a PNP transistor, fed from an internal IC-regulated −9 V DC, 50 mA supply. Students measure the voltage gain, plot the frequency response, and work out input impedance, output impedance, current gain and power gain. An audio frequency generator, decade resistance box, AC millivoltmeter and 20 MHz oscilloscope are needed for the experiments and are not part of the board. A printed guide covers the object, theory, design procedure and report format.

Where This Is Used
It is usually the first transistor amplifier practical, followed by the Emitter Follower (CC) with power supply (Product ID: 12133) and the Two Stage R-C Coupled Transistor Amplifier with power supply (Product ID: 12158). The board works from 230 V mains, so change patch cords only with the power switched off. Browse the full Electronics Engineering Lab Equipment range or related Electronics Lab Equipment products.
Frequently Asked Questions
Which transistor configuration is used?
Common emitter, with a PNP transistor.
Is a signal generator included?
No. An AF generator, decade resistance box, AC millivoltmeter and 20 MHz oscilloscope are needed separately.
What does it run on?
230 V AC, 50 Hz mains; the −9 V DC rail is generated on the board.
