Thank-you very much for the input. My existing build is trifilar with 18 gauge on the runs, 26 on the trigger, and the momentary switch definitely did the trick for starting it. you say "In this configuration you'll need very low input potential to start oscillator. It will charge in cloudy day." - that may be key to getting the solid state to startup unattended without the need for any overly elaborate PICAXE diagnostics, (and consequential programmed "triggering") etc. Simple is good.
This is my setup here.
@all
I've decided, gone are the days of ripping stuff apart, and starting over. The problem with this, is; as I see it: you don't end up with enough models to "compare", and thus you are forced to go by memory as to one working better than another, or you look back at your own youtube videos.
So I am going to build more, each time, I'm saying. On the other hand, I do like to "use what I have", to a great extent.
Now, I've taken some laughing and flack for this: but, this is my next attempt, and the main reason, was, I have the materials and they were cheap; very cheap.
And that is, aluminum magnet wire. I have 1000' of enamel coated transformer magnet wire. It is just that: transformer wire, not some hobby craft wire I bought.
To potentially bypass a whole bunch of back 'n force, I did a bit of research, and quite frankly I'm not the type to fret over $20.. if it works, great, if it doesn't it wont be the first nor the last $20 I spent/wasted. I'll quote a few things from Val-Tech Inc.
Aluminum wound transformers are lighter in weight than copper wound equivalents. < TRUE
Copper-wound low voltage transformers are better for "high-impact" loads because copper has higher tensile strength than aluminum. < FALSE
Aluminum-wound transformers have higher losses because copper is a better conductor. < FALSE
Aluminum-wound transformers have higher hot-spot temperatures because copper is a better thermal conductor than aluminum. < FALSE
"To keep the temperature below the insulation rating, aluminum transformers are designed with aluminum conductors of larger cross-sectional area than copper. On average, this results in energy losses that are the same for aluminum as for copper. Therefore, transformers of similar design with the same temperature rise have roughly equivalent losses regardless of conductor material. "
So arguments aside I am going to try it and risk all 20 dollars. I bartered the guy down, got a deal, it's in my hand. Similar copper would have costed me a fair bit more and I wanted to try this.
The 18 ga. wire is rated for 6A, whereas similar copper would be rated for 10A. I think from my experiences it's pretty safe to say the stuff is not going to see 6A per strand. And if it does, I'm probably doing something very wrong.
Both strands together in my existing SS circuit, combined create a draw of maximum 1.5A and when it runs at 100Hz, even, it doesn't get that warm, really.
So the question in my mind is not whether to use it or not, I am using it and I'll find out how it performs. The question is, instead 100' like the copper should i consider going shorter, longer?
Now am i thinking about this correctly, or not:
For a given number of feet of wire, aluminum being less conductive, will be more resistive, so one could shorten the length but then one would have less turns, unless the core was slightly reduced in size?
The easier answer would be "go higher gauge". But that's not an option, because I have bought the wire, but it is 18 gauge, not 23 or 24.
What are your thoughts? Please bear in mind, I'm building a desulphator, not a free energy device.
I look forward to building this and several more Bedinis before straying too far. Although on this variant I may wire it as a Tesla Oscillator circuit with cap and diode mode, as shown by 49'er who is pretty darn active at desulphating batteries.
I had planned on using a helical bobbin style form, though.
Thanks for any input!

It seems that your circuit choose this spot for a reason
) based on trifilar - transformer style coil. What that means is that coil has three windings with same type and length of wire, so it is like a transformer 1:1:1. While first two are connected in typical SSG (with exception - there is no output diode from collector) third winding is connected directly to the AC pins of bridge rectifier. Both, "+" and "-" are connected to the charging battery, according to polarity. I built a few variations of this circuit before, experimenting mainly with wire thickness and length. I found AWG#18 giving nice strong pulse and 100' length optimal.
