| - | The Results below are measured at 3ms Dwell Time and 14volts. | + | My circuit was built using a IRF740 N Mosfet a diode and 2 resistors, driven by a Frequency Generator and bench power supply. The LSX Coils were used with another box to drive them. Links included below for the coils purchased new. |
