Agreed Gadge...Ive found a few equivalent caps and diodes. But yeah the coil may be the hard bit,but ive an electrical engineer mate who designs lighting alarm and power systems,so ive got a foot in the door for parts....Yes the strip is plain brass and doesnt give like a bms...

Anyways im happy to give it a go,if all fails then ive got my spare on a runner but didnt want to swap it over to my display 35 as it will be wasted.
