i suggest using a separate power source for feeding the 2N3055.
high amps won't be gentle to your jt transistor, it won't be gentle to your 2N3055 neither.

to see what i mean, take a basic jt, but change the led location.

put the led, with right polarity, in parallel with the battery.
also try in series, the led hook to one side the battery, + and/or - side, then to the wire that would normally be hooked to the battery.
polarity of the led will matter.

it will be easyer to protect the 2N3055 base when using a separate power source.
also this way the 2N3055 will not interfere with the jt inner working.

If the location of the 3dr coil and timing is taken under consideration , it could be done , but the jt wouldn't be needed anymore , but electricity is only used to create a mag field , i well paced magnet could also do.

i just hate to clutter this thred but    lol


heres a DA TA BOOM!!!  LOL

use the out of 110vdc lol 

ok really im done guys ... 

ist!

ok GUY STOP SETTING ME OFF LOL !!  I MEAN IT ...


I HAVE DONE THIS ...   long time ago ... 

mk1 your right .......     i was able to place a magnet permantly on the coil ......  and when i applyed another there

the rest is history 

lets just say     it came ALIVE ..     LOL ...   THIS IS MY CAP CHARGER ......   I DID THIS B4 I KNEW WHAT I HAD ......  IT IS ALL OVER THIS SITE ...   EXCPT HOW IT IS DONE ....

this song fits.....

do listen to it

@ist

Do you mean Lorrie Matchett style , or just of the main one plug per house deal.

In this life we are defined by the way we make money , lets do it for all, and all for one !

I built another toroid of copper, as I said earlier and I can't get it to work at all.

I'm not sure what to do about the copper toroid - only the one I have pictured is working.  The latest winding was a fail.  This incorporated a coil, with a twisted pair wrapped around it.

Just to make sure my transistor worked, I built another linear transformer, and replaced my resistor up front with an LED and it lights up.  I've included a diagram of this circuit.  It's component-simple.  The linear transformer is 10 inches long - 26 gage wire - just a large free standing loop ( it's stiff enough to stand up and not fall over ).

Yes the JT would not need to be used, for instance, drive a rotary contact switch with a 1.5v toy motor, let the conuncator switch the coil in and out, the coil energises and de energises depending where the position of the comunitator is at the time.
But it is a bit more difficult controling the Mark Space ratio, but it is possible.

However, the JT is the timing electronics to do this.

@ ist
My friend, are you alright?    you seem extreamly excited today,,,,,    maby I have discovered something you are happy about? lol     
Yes BIG AMPERAGE can be GOT outa a 1.2volt NiCad battery, Heeps and Heeps, just short the cell out, watch out for the pinkies if you hold the bare wire between your fingers ha ha. 

I must buy a battery charger for the meter itself at the local scrap yard and try this again, fun fun fun time comeing up chaps. 

arrrrrh kaboom, it vill verk, velly goot, den ve ave mooooor powerrrrr, den vee no vot to dooo wiff it?. ya, make it vork.
