LM317T Voltage Regulator with Pass Transistor

Today we discharge 5.5kV 50uf into film capacitors, electrolytics, resistors, LEDs, surge protectors, 7805 regulator, power transistor, and a LED array from a dead flashlight. Nothing survives this kind of overload. The capacitors go off with quite a bang, they rip apart. The red LEDs disintegrate so quickly that there is nothing to show in slow motion. A small ferrite inductor had the coil blown clean off it with no harm to the core.
