Hehehe, I hold the record for something :) I think what was going on 
was some slight overcoupling, not enough to cause racing arcs, but 
enough to make the current peak slightly above the base of the coil. I 
was getting racing arcs at the start, but I raised the secondary 2" and 
this solved the problem. Perhaps the damage to the lower turns was 
alreay done but I didn't see it before it got serious??


Cheers

Greg.
