   In this particular setup the transistor is going to vibrate like a mofo.  In fact it is going to hit a whole bunch of freqs.  It will distribute an expotential rise in frequency and subsequent gain in amplitude at the expense of duty.  So you wont have the same voltage impressed across the load for a long time but a very high change in voltage across the load for a lot of shortened times.  Induced voltage is a result of change in the field about a conductor.  The faster you change it the higher the voltage.  The higher the voltage the faster you can change it. 
   Everyone has heard a flash charge circuit.  It starts off at a real low freq. and goes ultrasonic but it doesn't stop once our ears cant pick it up.  It goes way up there.  Hence the transformer needs to be able to respond to highfrequency to get the best bang for the buck.

     The relay when it's contacts approach each other and you have two capacitor plates squeezing charge into the space inbetween em the resulting plasma when the contacts short gives a very wide spectrum of pulses.  Your coil will pick one out and store it up for a while and shoot it back to the gap with alot more voltage than the little pulses that it sucked up.  Voltage begets voltage.

Here is what I see on my cro, I connected the earth clip to the 0v of the LED and the probe to the +v of the LED and up popped a image of the insides of the LED, well until I know more thats what it looks like, weird.
This reminds me when I was looking at the waveform of a video signal displayed on a Wave Form Monitor?? (not a vector scope)

OK photo 0205 = side view of the LED extinguished showing probes connected to anode and cathode.
      photo 0206 = Cro waveform showing image of LED, weird stuff this.
      photo 0207 = LED is ON
      photo 0208 = waveform when LED is on   
      photo 0209 = Close up at ringing at bottom of trace

OK photo 0210 = LED is off, probe connected before switch to both ends of coil "a"
      photo 0211 = wave form of open circuit, no load, at ends of coil "a"
                          notice there is ringing at top of trace and also at bottom of trace.
 
@Rensteak,
Welcome to the forum.
So you built a JT with a ferite rod out of a radio, now thats excellent.
How did you wind the bifilar coil, how many turns, could you post a photo please
could you draw up the circuit and post it.

Well done Norbert

I have to sestart my PC its locked up hope this gets to forum ok.

indeed but!

even 1 bang from this buck ... lol

and it hurts with out a cap  ... if you use a cap this can be fatial in 1 pulse ...  depending on the cercimstances..     ...

so i will not even run the thing as fast as my relays can go....... way too fast!!!!

to really grasp this entire thing you must solve conversion....    then use the ozone layout to selfsustain ...

like i said b4 i never studied the last pattend...

ist!

ok   SPARKS....   but what if it could never return to the gap 

dont think youll blow anything  and it will find it's own path of least resistance on its way to ground and what if it was 10 light bulbs .... 



i do perfer to put it in a battery and use an invertor     lol   well until i finish my new IST'S CAPPAC! lol then i will drive the invertor right off it with out batteries .......  lol closed loop 

as i said b4   YOUR MIND IS YOUR ONLY LIMITING FACTOR....

peace to all

@electicme

Don't get confused with led,those led are giving about 1.4 volts dc in full sun light, the scope is showing the light reflection in the led.
Check to see how right i am.I have not check it with scope.Led are like solar cell.You got a scope of free energy, lol.

@all
Just rebooted the old PC, had a software update in the background, so I used ERUNT to make a copy of the registry as a safety thing

Right, I checked the forum and I was right, the cro shots didnt appear so here they are, 2nd time lucky ehhh.

@ Bill
I got your PM, thanks kind sir.

right, 0206 = inside of LED can be seen on the cro screen, weird
        0207 = LED side on view to see its insides, sorry its not too clear.
        0208 = Waveform of output of coil "a" whilst LED is turned on, one can just see some ringing on the bottom of the screen
        0209 = closest I can get to make the ringing bigger.
