Push Pull Amplifier Manufacturer,Supplier and Exporter in India
Product Code : EL-AET-1451
Jlab Export is a leading Push Pull Amplifier Manufacturer,and suppliers in India
Push Pull Amplifier (code EL-AET-1451) is an analog electronics training board for studying a class B transistor push-pull amplifier at audio frequencies — measuring its output power, plotting its frequency response and measuring distortion. The circuit uses three PNP transistors with a driver transformer and an output transformer, runs from a built-in −9 V regulated supply and has four output loads on a band switch. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Push Pull Amplifier Board Used For?
A class B push-pull stage is a common way to drive a loudspeaker or other low-impedance load efficiently: each output transistor conducts for one half of the signal cycle and almost no current flows with no signal, so efficiency is much higher than in a class A stage. In the classic transformer-coupled version, the driver transformer feeds the two output transistors in antiphase and the output transformer combines their half-cycles in the load. On this board students measure the output power, plot the response across the audio range and measure distortion — a regular power-amplifier practical in diploma, BSc electronics and engineering analog electronics labs.
Frequently Asked Questions
Why is distortion measured on a class B amplifier?
Because a transistor does not start conducting until its base–emitter voltage reaches a small threshold, a pure class B stage leaves a short gap each time the signal passes through zero. This crossover distortion is the main weakness of class B operation, so measuring it is part of understanding the circuit.
What are the four output loads for?
Switching between them with the band switch shows how the output power delivered by the amplifier changes with the load connected to it.
What other apparatus is needed with the board?
A decade audio frequency generator, an AC millivoltmeter and an output power meter. JLab’s audio signal generator and AC millivoltmeter are separate items, linked below, that can be quoted on the same enquiry.
How does it differ from the other JLab push-pull trainers?
The Push Pull Amplifier in the Amplifiers Kits range covers the output gain and frequency response of a class B push-pull amplifier, and the BJT Amplifiers and Emitter Follower Trainer covers the differential amplifier and class B push-pull amplifier with +12 V and +5 V supplies and an in-built sine-wave generator. This board covers output power, frequency response and distortion measurement.
What information is needed for an export quotation?
The number of boards, the destination country and port or city, delivery terms such as FOB or CIF, and any packing, labelling or tender requirements.
Who manufactures this Push Pull Amplifier?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronics trainer and laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The board comes from JLab’s own works rather than from a trader, so colleges, institutes, dealers and importers buy it factory-direct, each board is visually inspected before dispatch, and repeat orders go back to the same manufacturer. JLab exports worldwide and ships to buyers in every region — Ireland in Western Europe, Angola in Central Africa, Mexico in North America, Samoa in Oceania and Nigeria in West Africa are examples. Tender information is on the JLab lab tenders page.
