"To form low inductance primary; wind 5 turns of enameled 18AWG wire (1mm diameter) on the core. Secure it with tape or glue at your choice. "
"To form feedback winding use 22AWG wire (0.64mm diameter) and wind 2 turns (or 3-4 turns depending on your transistor's Hfe) then secure it."
"The value for R1 is for 24-32 volts operation. You may replace it with a lower value like 110 ohms for lower voltages. But 240 ohms will operate the circuit without any problems. As the input voltage rises the power consumption on R2 (27 ohms) increases. Although it seems won't become hot as much as R1 according to ohms law, current inducted on feedback winding uses R2 to reach the ground and this should be added to the calculation. So check it's temperature and use a higher wattage one if necessary.
Be sure that your power supply is capable of giving the 2-3 amps current as circuit will take. Set two cables in clearance of about 1mm at their tips to observe high voltage output from the secondary leads. This is an initial gap length to be sure. Please use a push button type switch since it would stop the circuit as you take your finger away. This is a legitimate precaution and the circuit should never be operated while it is constantly connected to the power supply. As you understood the security reasons well, apply the power by pressing the button. Now you should be able to see the sparkings. If not, and your multimeter shows that the circuit is already dragging 1-2 amps (or more) current then it's just the feedback leads you have to reverse. Now your mini monster should be working. "
znači, radi se o najglupljem vn trafou iz crnobelog tv ili monitora koji nema u sebi diode već prosti sekundar. originalni primar se iseče i baci a namota se kako je rečeno.
