Ready for some Spitzensparken?
Be sure to use a very good cap, that can withstand the hight currents when discharging. The parts are not critical, any transistor, that can handle the power will do and the resistor values are just for orientation.
Have fun watching!
The whole arrangement will make a top voltage of about 400 V with two secodaries at 24 V, you can go muuuuuuuch higher with lower values and resistor values. In my very first tesla-coil almost the same arrangement makes somewhat 4 KV.
Here came my inspiration from.
See you then!
