You find here, a picture of a prototype of an amplifier.
This project is developted for my students. It is base on the NXP’s TDA8551 ic.
In the datasheet one find a application schematic. This schema is modified so the tuner can be controlled by an µcontroller like the Arduino UNO.
This project is only with SMD parts so the students have to use solderpaste and a solderwave oven to solder there amplifier.
