  1. sir hpw to I make gakun controll.... please reply

  2. U can buy it at online shop . But this product is only popular in indonesia .I have never seen this product outside Indonesia

  3. Can you provide the commercial part numbers for the Gacun module and TR1 and TR2?

  4. Please add pcb layout.thank you

  5. Podria ser posible mas datos de la fuente o video de como la construye como los exelentes videos que he visto sube. Desde ya gracias desde Argentina

  6. Sir can u sent me the details of Sm transformer construction
    I want make different power Sm transformer

  7. untuk lilitan primer dan sekunder ukuran kawatnya brp mm?

  8. Hello brother it's me Sandeep Ur old friend, first me try to assemble 4k5amp ,many MOSFET are damnege ,the brother u the amplifier is working super,now i want to make this gacun smps .pls tell me the primary wire swg and need any air gap to to winding , thanks brother +918921058775 whats app India

    1. This circuit is not compatible with D4K5 amplifier
