[TowerTalk] re; Whiskers growing where you cannot shave them

[TexasRF@aol.com]

Hi all,
 
Another place this shows up occasionally is in high voltage door knob  
capacitors. This was pointed out by Bob Sutherland, W6PO, many years ago, and he  
called it silver migration. 
 
Wonder if this phenomena could be responsible for some of the power tube  
flashovers we have seen from time to time? Could be the flashover blows away the  
"whisker" and all is ok for a long period of time afterwards.
