Power Amplifier Micro Driver

This time I will share about the power micro driver or super mini power with great power for the driver. This power circuit is capable of up to 75V DC symmetrical, Where this micro power amplifier can produce incredible power up to 1000W if properly coupled and using a good power supply is minimal to big power out, the current intended for this power is 20Ampere, although the power amplifier is quite simple with a less complex circuit schemes, which you can see in the picture below and see also the PCB Layout Design:

The circuit above is the only driver circuit so you have to add the final transistor as 2sc5200 2sa1943 10set much or more to add more power output. Or see final transistor power amplifier list.

Here for PCB layout that can be used as I design and later made to the size of 85mm x 62,5mm.
