Re: [TCML] pole pig question

I have blown holes in 2 or 3 big 9 inch ceramic resistors. I can't clearly 
remember the circumstances except it was in the primary of my 4 MOT supply. 
I might have been charging a big cap to augment the supply.
I assumed that this was an inductive problem with fast transients at the 
time since there must be hundreds of turns on there. It wasn't an 
overheating/power problem as these were 100W rated and didn't get hot.
