Hi,

I just had to try out John's instructions on how to obtain sparks and WOW; this is new to me; holding a well insulated screwdriver near the single wire of U25 I could draw a thin spark out at around 1/2" long but holding a thick plastic handled with an exposed blade and pressing the blade to the LOPT surround whilst advancing the tip towards the double wire end of U25 I could draw out a thin spark up to about 1" long from each wire; there certainly is some life on all three wires. Many thanks John I found it highly entertaining. I ensured I only held the screwdriver handle at the end with two fingers keeping my hands well away from the blade and any other metalwork.

Kind regards, Col.
