Like what do you mean by better? what is better? does that mean the voltage is higher? Since you don't have a scope you don't actually know what the frequency is... how do you know it doesn't kill the frequency. Are there results you could tell us?

I think I can help  out   a little here .

He means  it is better

Seriously
I only used my3055 on a couple  of   coils  before  I fried it/
I did not  write  all the details  down ..... but I remember I kept thinking    WOW this is  better   
I am  pretty sure the current  draw was down
The  JT light  was brigher
My output  voltage was  up I think  about 20 V on one coil .  (maybe  10% better )


The  3055 is  a higher power  transistor.
My  guess  about what  is going on is  kind  of like opening  a door .
The  3055 has a bigger door ...... and  bigger seems to be better in this case .
I have not  ordered   any more  3055s  ......but I plan on  ordering  a handfull of them soon   ............because they are better

My Latest Creation . 48 1 watt leds , well 47 and 1/2 . It was so bright it blew one so i had to crank it back a bit .
1 aa battery at 10 ma compared to 3 aa wide open amps  . a 200% improvement or more if i do say so . I love light s . I must have Mexican in me Standard jt with one of my special Germanium's and a small toroid from a PS. This sucker is as bright as a 60 watt light bulb . It was a good find at the flea market this morning for 3 bucks!!! I turned a 3 dollar light into an Expensive  energy device . Im running it and see how long she goes ! I'm also using Bedini recharged non-rechargables . I have recharged this one all year long . I got 4 of them and i use them in the camera i take pictures here with .

That looks  great   

I am still  working at getting my  60 LED array  up to  full power .
What  was  the  numbers for your wraps ?

The best   ones  I have done  are clearly  in resonance ....... they hit  a sweet spot  and  the  lights get bright and the  current draw  drops way down .

The  problem with this is  it is not   stable .   when  anything  changes   a little   it drops out of the sweet spot.

Do  you have this  kind of problem with yours?

Yes, better. It is just a whole lot lot more helpful to throw in some details, like the things that made the system produce different (better and worse) results along the way to better.
We are doing research here (not applying for grants. )
We can help each other.
Others can benefit from our mistakes as well as our successes.

I believe in this kind of exchange and I want to see it work so I give all the details (well more than anyone wants to read anyway)
Like the linux community the open source works this way.
Like the ocean, and the earth and the ground... oh dear, now I am getting poetic.

Thank you Gary,
I can agree today.
I have finally had success with the 2N3055.
And the success came from the fact that I have switched the larger number coil into the base coil spot out of the collector coil spot.

@xee, I am glad to see you are here today, because this could mean an important modification to your theory... I think, anyway.

Here is what I can say for now:
1.2v battery
BJTLed in its spot throughout til the end
13T,3T,240T biggo
2N3055
5kpot

The bjtled barely lit at 4k ohm, so I am considering that the highest resistor end. So the full range was:
4000r       179v    13.3KHz
    92r       449v     5.4KHz
As I continued to change the resistor past 92r,  the voltage went down and up and did not return to the same place when I took the battery out and in again, so I am considering this the lowest resistance usable.

Right about here I noticed the whine. I have not heard the whine with any toroids yet.
I have a lot of white noise in my house, and maybe have just missed it, but today it was very audible.
It was lowdest at around
45r    456v-475v     4.65-4.16KHz then got quiet again. still there but lower volume?

The led became uncomfortably bright at about
247r   producing 375v      @6.89KHz

This feels like a day to light a fluorescent light.

One more thing. I took the light out and before I put it onto the scope, I looked at the voltage in the vac of the dmm.
It said 89v-93vac it kept moving too.
The sound became noticeable and the numbers were
45r    456v-475v     4.65-4.16KHz as I just reported above. I think I should re-check the numbers without the led at the 92r spot, just to see if it is the best spot without the led and maybe produces 475v instead of 449v.
