TDA7492 Mini Power Amplifier + ower Supply (110V-240V) 50W+50W
- coupling capacitors used Siemens capacitors 0.47UF, the main filter electrolytic
- Capacity usethe Philips brand, the capacity is 2200UF/25VUF * 2, TO ensure strong stream of power.
- Resistance selecte the five rings metal resistance, the main circuit use ± 1% of the five rings accuracy .Metal film resistors, to ensure a good signal. the PCB use 1.6mm thick double-sided sheet thickness of 2.0 oz copper spray tin process to ensure the good performance of the current, the higher quality for the PCB. (The amplifier board rational design and the sound up to the maximum with 4 ohms the speaker voice continued.
