If you want build hi-fi power amplifier about 30watt to 50Watt or 75 watt. Recommend use TDA2050 below, builds by the integrated circuit and PCB layout.[...]
Do you want low-frequency class B power amplifier? See TDA2020 may be one of choice that you not should miss. Gives 20W to 80W with helping from a transistor.
Good transistor audio amplifier circuit, at 40 watts OCL RMS using 2N3055+MJ2955 is easy to build,and very inexpensive. To use Power Supply +35V -35V 2A.
This 50W OCL main amplifier circuit has high quality and economical,it is designed simple,easily created, electronics rookie.cheap when compared to other
The integrated amplifier that is smaller. For listening in a small room. Must have good the sound quality. Low noise and cheap.
A friend takes an interest to want to try build hi-fi power Amplifier the some one. He likes model class AB , because the sound is good. keen bass good…
Simple MOSFET Amplifier Circuit easy make!
