SM expose'

[poynt99]

Is this a shot of the elusive "kicks" or just a transformer coming out of saturation? You decide.

i'd say the latter

what's your setup please?

let me take a stab;

sine on primary, input is biased positive. scope on secondary?

It is just a tranformer comming out of saturation.
The kicks are not that perfect in amplitude each time, in fact it displays a quite irregular pattern.

Try again.

When I saw Marco's waveform, I new I'd seen that before, so I set out to duplicate it without the 5U4 circuit. I will try the 5U4 circuit soon. Marco's signal has other modulation on it producing an irregular waveform but since he's reluctant to supply a schematic, I thought I'd do a little playing on the bench to try to get close with a very simple common mode choke. I can make them irregular with a few twists. I was shooting for the very first waveform posted next to the four transformers and somebody in a weird suit.

Here it is

The irregular display that i am talking about isn't in any of the scope shots i have been posting.
You see you can try to test me, but my feeling never lies.
Nothing is what it seems....
You have to do better then this.
Why don't you show me some REAL kicks?

marco,

i think your "irregular pattern" comes from the whole thing riding on a much lower frequency.
