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:

Sir ,I'm from India. MUR8060 is not available here. Which diode I can use instead of MUR8060?

sir , is it ETD-34 transformer ???

Please give number of turns and diameter of TR3 Pin 3,4 winding and 5,6 winding.

Specification of Gacun Trafo MK201609

hi sir
i cant find the gacun trafo can i wind it my self?
what etd core should be used for max performans?

Brother pls upload this amps 75/0/75 25A video pls

Bro layout atas kok tlisanya gak di blik.

Ajarin lilit travonya mas
Dobel NP apa gimana, pakai kawat uk berapa,dan kalau pakai travo bekas psu pc yang belalai brapa lilit

hi brother, do you gerb file?

hi brother, do you have gerb file?
