["brand new and high quality\r\nColor: See pictures\r\nUse: Experiment, electronic instrument, negative ion generator,scientific production, etc..\r\nThis circuit works to produce a stable high frequency arc, high temperature, can easily ignite the fuel\r\nSize: 20x17x15mm/0.78\"x0.67\"x0.59\" (L*for W*H)\r\nThe transformer is also suitable for 12V voltage, but requires increased base feedback resistor to about 150 ohms ~1.5K for Omega, the resistance should be large to small replacing and adjusting, not can be too small, otherwise burn triode or transformer, also should not be too large, too large affect output or the triode tube works in non switch state and severe fever.\r\nTransformer Design for the highest output of 10KV, the maximum output of the limit shall not exceed 15KV, that is, 1.5 for cm arc, the higher the output voltage is highly likely to damage the transformer.\r\nIf you want to be reliable and long-term continuous work, it is recommended to use insulating wax or epoxy resin will be completely sealed, no for time to seal the work of no load!\r\nNo Retail Packages\r\nQuantity: 1pc\r\nNote: Due to the difference between different monitors, the picture may not reflect  the actual color of the item. Thank you!"]
