This power board is designed for Class A power amplifier board with rectifier board filtering
Regarding the selection of the voltage level of the main power supply in the current amplification circuit:
Due to the non-linear operation of Class A power amplifiers, if the voltage is too high, the stability will deteriorate and the heat generation will also increase. Therefore, low voltage power supply can be chosen, which not only works stably but also can adjust to a larger current. However, the disadvantage is that the power will decrease. Therefore, the user determines the voltage of the main power supply according to their own needs.
