Mh with over 1000 pages on the Jt topic we have already determined the the best and cheapest core a long time ago  and also provided a way to tune those cores to their resonate frequency and there for maximizing the battery life and efficiency . I am experimenting with a 140 mm (5.51")W core right now . With just 6 turns it has taken out 5 transistors and 4 leds and with just 7 turns a secondary it lights over 20 leds to maximum overdrive from very little input from an aa battery and also lights one from the B C junction and the C E junction all at the same time .  Not athing new here as jeanna,Mk1 ,Xee2, groundloop, and others have already documents 1000's of experiments finding the best of the  best and the worst of the wort . It boils down to high permeability /low flux toroids are the best for a JT . We also have suppliers for as low as 5/$1 and giant 3.3/4 for 2 bucks each!

Milehigh is on the ignore list of a lot of people. He's on my ignore list because he's filled with a lot of half truths, and he's an out right  liar. He'll twist the truth, make up stuff just to inflate his ego. I feel bad for the guy.

Albert:

I have a feeling that I brought a lot of interesting issues to the table that may not have been raised before.  Cores themselves don't have a resonant frequency.  It's the coil inductances in combination with the toroid core and the transistor that determine the resonant frequency.

What a load of crap and don't you dare call me a liar.  Anybody that reads this thread from start  to finish can decide for themselves who is telling the truth and who is lying.

You are so Orwellian that it is almost scary.  You are a junior amateur electronics guy with blinders on obscuring 75% of your vision sitting in your little Orwellian fishbowl filled with murky water.

The AAA is recharged again. Lets give this another whirl.

id just like to say thank you to MH!

we must realize each and everyones importance ..  and this im sure MH  understands  !

so we will carry on in the safest mannor ...

thank you
