Ultima_gtr,

That's a great read......I take it then that you are in the snakeoil corner then ?

DANewsome,
Thanks also for your input. Equally interesting.

Both spot on with what I was wanting to get to. Now...

Would you two guys mind slugging it out for a while to see which theory gives in or indeed if the converge ?

Blue corner is snakeoil & capacitors
Red corner is dielectrics etc

Rgds,
Nick
