    250w Power Audio Amplifier Circuit Diagram V3

    The amplifier is adapted to mount the transistors on the PCB, which only improves the strength and stability of the amplifier, as the conductors that lead to transistors are often not the shortest and have their own inductance and parasitic capacity. In this case, this problem is not necessary...

    Automotive 12V to +-20V converter (for audio amplifier)

    The limitation of car supply voltage (12V) forces to convert the voltages to higher in order to power audio amplifiers. In fact the max audio power x speaker (with 4 ohm impedance) using 12V is (Vsupply+ - Vsupply-)^2/(8*impedance) 12^2/32 = 4.5Watts per channel, that is...
