> I'm not sure about that "filament/heater" difference.

Filaments used to be called heaters until someone decided they should be
called filaments.  They're heaters because that's their function, to get
really, really hot to allow for electron flow.  (Yeah, I know about the
whole hole vs. electron argument.  Obviously I'm old school.)  Again, this
is an example of change for the sake of change.  We still talk about
directly heated vs. indirectly heated tubes, not directly vs. indirectly
filamented ones so, again, let's be consistent.  

Surely someone will come up with an argument that says how they're really
filaments and calling them heaters is wrongity-wrong but ... well, they can
recall my previous comments regarding mistletoe.  :-D
