Sorry, I wasn't making myself clear. You are quite right of course. I
might also have botched some calculations I sent in another post.
Club me with them if you like. I was trying to make the point that
the energy delivery of the transformer can be seen to be limited,
even if the cap is set for mains resonance. See my post on this. I
think the calcs are actually OK, just an assertion about the firing
rate. Anyhow, check out my argument.
Cheers,
Malcolm
