Super quality PCB. Solder pads are corrosion resistant. Soldering quality is very important in audio and high-frequency circuits. Thanks to the quality lead finishing on the Pads on the PCB, the soldering process is high quality. PCB quality greatly increases the operating performance of such circuits.
*This is 500 Watt mono amplifier using IRFP260N MOSFET and TL494 IC.
*For make coil of this amplifier, must use LCR meter. Because 50% sound clarity is depended on it's coil, and 50% on circuit.
*Wrong coil can getting hot, and it may burn out MOSFET.
*This amplifier can work minimum 24VDC. But for get best performance of this amplifier, you use 45VDC-50VDC 10-12A SMPS power supply.
