It is a simple HI-FI power amplifier 2x32W based on TDA2050. The amplifier consists of small number of components, so it can be easily performed by beginners. Although it is very simple device, interferences are really small: 0,5% THD – AB class.
Schematic of the amplifier can be found in the note sheet of the system: LINK.
5A transformer used in this project gives about 14V voltage. Very simple power supply made of Graetz bridge and 4700uF/35V capacitor was applied in this design.
Although the device uses a small heat sink, circuits do not heat up too much (about 60-70 degrees Celsius).
Parameters:
- power: 2x32W
- interferences: 0,5% THD
- system with thermal and short circuit protection
- 12-20V supply
