Thanks.Seems I resolved problem by placing irf630 between emitter and ground of mje13007 and driving it from oscillator type. Because I'm not good in electronics it took me two days to construct circuit and probably will take another two to make a board in copper. I wonder if I can check the output waveform somehow without damaging scope ?
