@Jeanna, what does the waveform look like without rectification?

It looks different every time.
The only thing that has ever happened when there is something across the C-E is the voltage on the secondary is way down.
I have not made this one yet, but there is rarely something in that C-E position when I look, so I will see, because this is a very interesting question. It may tell us something.

I could try it tonight sort of, but I will do it in the day so tomorrow.

Thank you, as soon as I can afford a scope I'll probably get one.  I want to see what goes on across a coil NOT integrated into the oscillation mechanism, such as gadget's indicator light..just a reading on the bare wires.  Unrectified, I have a feeling it will look something like this, with a higher forward then back, just depending on the polarity of the probes.

for 1 your wave form depends on many things...

i had perfect sine 680 v

you see this can be built literly 1000 ways

i choose a simple design for a advanced coil ... beond anything patened yet that im even close to aware of

i garentee you my work is yet un matched !

this is like i said long time a go my BABY TOYS...

when i start mutible freqs...   yikes ..  i have posted youtube videos long ago ..   ist 5555 coil

this one im building  puts that one to shame ... lol   and its 2 freq 3 phase npn /pnp or eather

any how ... 

its only 1 tiny coil ...  it packs 1 heck of a punch of understanding ... 

w

get my message yet ?

WORLD PEACE ... NO MORE FIGHTING ...

many problems exsist in the cosmos as a result of your silly human actions ..

i was born on earth i was dumb as hell too ...  but i woke up ..... 


of course your gonna think im nuts cooco luni crakpot  or whatever ... this is because you havent done 1 lick of reserch ... or your trying to hide the truth of creation ...

i have spent years at what i do .. 

i have a gift of vision i have had my life

you speek it i see it ya know.... 

i encourage you digg deep i am not wrong ..  it is possible i may be on a string of sorts ... i have no idea nor means to check .. all i know is if it feels right good chances it is ...

2 things in creation love and hate ..  god has 2 faces ... it must be so ...

this is where it gets messed up ...   and i aint gonna go there 

please i encourge you all to come to your own conclusions im not force feeding  on you .. only shareing what i have gone through as i well know all walk the same path that i just have ... 

lets call it a tip  btw im a beleaver not a deciever ... good thing i choose the right path...

but i really hate spoon feeding but times up!

Where is the baseline in your photo?, and honestly, I don't know what i'm looking at, I can see that the upper angle is steeper than the lower angle, does this confirm my hypothesis?

I understand what you mean, depending upon the coil configuration, the wave would be conformant to the design.

However, on a symmetrical basis, the current flowing through to the base would be less than the current flowing to the collector when in the on position, it seems reasonable to assume that any non integrated secondaries would be more powerful in one direction than in the other based on the differing current characteristics in the primary coils; I realize that the design can overcome this.
