I have'nt tried either... As far as I know about the meg, what is important is to get fast switching. Faster you go, the better it should be (as said in the ...

No, because my meg was started as a project with some high school kids last year... we got it built and just started testing and the school year ended. By then...

In looking at your output waveforms, it appears that your MEG is still a "Biased transformer". Note the skewed output waveform. Try changing the input...
