?   Good point.  Through-bolt mtg. also blocks cooling air.  100k 
wirewound resistors are known to have a high failure rate.  If I wanted a 
Reliable bleeder for a 4kV C-filter supply, I would series up 8 to 10 
Matsushita/Panasonic 100k-ohm, 3w MOF resistors on a piece of perfboard 
and be done with it.
