I don't think Carl is making a personal comment, Tom.   During the vhf 
parasitics debate, there were a number of issues you tap danced around.  
You appear to be on the same course in this discussion. .

The problem is that the tubes which have the problem typically do not 
show signs of abnornal gas.  Out of the 5, kaput 3-500Zs we tested 
Monday, none appeared to have a gas problem.  However, all of them had 
bent filament helices  If gas was the cause of the problem, where did the 
gas vanish to?
