THIS TUTORIAL NOTE IS FOR BEGINNERS, EXPERIENCE IS NEEDED. RISK OF ELETRIC SHOCK AND FIRE.

After disassemble the lamp discharge all capacitors of circuit. With a 4K7/5W resistor in paralell of the caps.
Get a burnt flourescent lamp. More watts is best, i used in this project 30 watts reactor lamp.
To test the lamp observe the filaments should be darkened.
The effective test is done with the multimeter in the ohmic range.
to energize the circuit use a series lamp halogen or in
incandescent. "the light bulb series trick"
That is twice the power circuit. For sample Circuit 40 Watts consumption. 80 watts is lamp.
The ressonance of some circuits are high and ferrite transformer will be hot, wasting energy. Keep cold the transforme using a fan 3,3 or 5 volts widing have a few volts to energize the cooler.

Step 1: The Circuit

ALL INFORMATION ARE SHOWS IN ANNOTATIONS IN THE FIGURES

the figures show the schematic to modify the circuit.

do not disassemble the atx power supply transformer. Coming soon i make a tutorial to disassemble the ferrite transformers with hot air.
the transistors use aluminium heat sink. it is an original AT obsolete power supply. use complete heat sink or saw in 2 pieces.
use fuse in input according the current and power.
this project dont have protect for short circuit, this is an auto-oscillating circuit and disable by short in output reducing the feed-back.
