Hi Ed,

Seems like the real factor with this issue is not necessarily the power
levels but the winding height relative to the power level.  Lower aspect
coils will have a greater problem than higher ones (everything else the
same).  I would also think the coil form material would play some part in
this in conjuction with the humidity and other environmental factors.

Using a nylon screw to terminate certainly helps.

Question:  Is it easier for an arc to travel down the inside of the form
than the outside (everything else being the same)?
