Partnered Output Coils - Builders Group - Moderated!

Here's an old POC(will update with better schematic,  my L3 connection is backwards in drawing) I made and came back to after getting a better understanding of circuits, impedance,  and the reaction of my coils, etc... still have a ways to go. But this setup is very simple, if anyone can give me a better way of checking my results(proper measurements etc.) or if I got it wrong,  point me in the right direction. I've learned alot following Chris's work, and direct hints(tho most are looking for him to make it work for them or explicit explanations of what to do in each case. Tho he's already gave them). There is still ALOT I haven't looked at that could possibly improve results(check L1 for resonance, changing loads, etc...) Any tips appreciated, will update with coil specs soon.

Updated pic, L3 still backwards, but pic of core above is correct. I was shooting for the 3.5watts the bulb is rated for, and used Don Smith's formula (cps=Volt amps * C)-think that's right- to get frequency needed. Tho, may not be applicable but actual frequency is about equal to: sqrt(((3.5watt/400pF)/20))) = 20.916khz. Random typing in calc. I'm sure my measurements are off, but it's a good start. Last pic is with probes behind diodes to see waveforms.

AU,

Could you please resize your attachments to fit the typical screen size.  Usually 800 pixels in width does just fine.

It is extremely difficult to follow along!

Resized, sorry dont have time to get on computer, just posting from phone, lemme know if you can make those out.
