Hi all,

I try to make this circuit but I can read AC or DC voltage in the output of this. What transistor must I use? I used the BU 508A darlincton transistor Also I test it with 2N1711 with MOSFET IRF 634A. firts, I usd in the output coils very smaller wire from transformer 264 turns and the input coils 16 turns I have build with  1mm wire.In the second effort I used coil from utp , telephone wire, the two output coils is about 45 turns and the two input coils is about 15 turns.
