DRSSTC schematic for simulating (primary feedback self-oscillating)

[VNTC]

    After run simulating several hundred  times with old schematic , I am very tired because after chang the value of  L,C i have to find  it’s resonance frequency at that case then set the periods of input signal  matching the loop of oscillations, that is to do many things.
     I am very happy when succeed in design a schematic that it can run oscillation by itself every change any value of component. This matter is very helpful because reduce 80% thing to do in learning Tesla coil.
 I think this schematic also can apply in practice ,but need to modifier something at GDT transformer, it is simpler the electric circuit a little, especially haft bridge running  in single bus, make more simple and advantage in rectifier and filter.
    Now, I think the big matter need to make clear is find out the best equivalent circuit of the corona, the spark in lite, medium and heavy load. This thing helpful in making the simulating give the result more accuracy.
