I am trying to made a mini tesla coil with d882 transistor. 0.3mm cupper wire (300 turns), 4 batterys 1.5v to make a 6v power supply, 22k resistor and a light bulb for testing. When I connect everything together, the d882 transistor become very hot, so I guess it still working. But when I put the light bulb closer to the tesla coil, nothing happen, the bulb is not light up. I try to change the secondary coil between 3 turns, 4 turns and 2 turns. Buti it still not working. I watched two videos about this, they can do that with d882 transistor and a 5-6v battery. So what is exactly problem here ?
This is my circult board.
