Younger brothers and sisters a student takes an interest to build electronics project sends a teacher. I then choose this circuit , because build easy be valuable certainly. It is…
Circuit diagram of TDA2020 power amplifier 80W hi-fi, For this application the maximum value of V1 in no-load condition is +/- 45V
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.[...]
I like mini power amplifier less 100W because it is low cost and easy to make project.
The integrated amplifier that is smaller. For listening in a small room. Must have good the sound quality. Low noise and cheap.
