Gomez,
The new bank is more intune with this old primary and has capacitance of
.01uF and still massive RF interference and now after repairing my
ground...5mm sparks and about 50cm to make a neon light glow. I am going to
recoil the primary with a new type of copper wire...30AWG and re tune it and
see what happens......also I will try to make a torroid out of a bycicle wheel.

Sorry to mislead you all!!! I didnt realise this.
