SMPS Power Amplifier using 2 Mosfet Transistor

This is power supply circuit using the power amplifier, like before schematic circuit SMPS Gacun here: 10A 70V SMPS for Power Amplifier there are using 1 Mosfet N Channel. This power supply circuit is suitable for power amplifier circuit with big power, can be used for a power amplifier with 1000Watt or more power. The maximum voltage that can be set up is 75V with maximum ampere can reach 25Ampere. By using 2 mosfet Gacun SMPS can add their output power and also stronger for all types of amplifiers. Below for the circuit scheme:
