You could start by an apology ...

i owe nobody nothing ... YAWN....

Magnets act funny on a torroid i found and they actually detune a circuit from resonance so my thinking was detune it with the magnet and retune it with the wire length not using any tank circuit but the wire it self.

I wish you could elaborate on that part , to me it seems mist by most people .

(retune it with the wire length not using any tank circuit but the wire it self.)

Thanks

Here's a new video of 2 Funsaver chips lighting a cool white toroid to full brightness with 2 AA's. The toroid lamp has 4 electrodes.

I agree with Gadgetmalls  answer
A capacitor is your answer.

To explain a little more........ your  earth battery has a pretty good output.......but that output is continuous.
It is enough to light a few LEDs
A JT works a little different ........it is pulses.
The JT may take less power overall ..........but when it turns on......it turns on hard.......the transistor conducts alot for a very brief time.
It is that brief high power pulse that is giving you problems
A capacitor  across the battery will allow the earth battery to continuously charge the capacitor........ the capacitor  will then provide a flow of energy with enough depth to handle  the high current  pulses


gary.

Thanks to Gadgetmalls & resonanceman for advise. I dont have any caps with me now so have to wait till monday to get it. Nervous and eager to c the result!!

sorry to ask this, but where i supposed to connect my caps?

Those 12V and 0.3mA come from 27 units of EB connect in series with adding dilute salt solution So currently finding ways to increase those ampere. Any suggestion instead of using salt?

Thanks
