This Fix-It Guide on amplifier repair tells how an audio amplifier works, what often goes wrong, how to identify an amplifier problem, and what parts and tools you will need to fix it. It then gives simple step-by-step instructions for how to disassemble an amplifier and tells how to in...
Your amplifier or home stereo has three main components: preamp, power amp and speaker. Your preamp converts the audio signal into an electrical current. Your power amplifier receives the electrical current from the preamp and adds voltage before sending the signal to the speakers. If there is ...
Amplifiers boost the power of audio signals using transistors, which are made from semiconductors like silicon that have been modified through a process called doping. The transistor in an amplifier typically involves a three-layer structure with p-type and n-type semiconductors, allowing it to cont...

These stages primarily may consist of power devices like thepower BJTs or MOSFETs. Normally, single BJTs become sufficient for getting moderate output current, however when higher output current is required, it becomes necessary to add more number of these devices together. Therefore it becomes neces...
