      hindi ko kc masa2bi sayo ung tamang voltage na bias boss kc nga ung mga amplifier iba iba bias nyan.gawin mo sukatin mo.dapat BASE TO EMITER.parepareho dapat sukat nyan. negative to positive

      Una mong e check ung power suply nya
      E check mo mga diode resistor malapit sa coil nya e check mo lahat ng mga pyesa nya banda sa coil.pati narin ung mismong coper bord nya e check monarin.baka meron cut ung coper bord nya.
      Ngayon.kung hindi parin nakuha don.e check mo mabuti ung mga mosfet nya.
      Meron mosfet yan.ang mospet boss hindi katulad ang mga transistor pag dating sa pag test ng parts iba ung pag test sa mga mospet sa trasistor.e check mo mabuti ung mga parts nya lalo na ung mga mosfet aat transistor.diode.resistor.e check mo mabuti ung mga parts nayan.
