Hi Everyone,

Does anyone have an opinion on which filament type is better for H/D work 
Tungsten, Yttria or Thoria?  Apart from the fact that they have to be run 
on different currents I have no information on which is preferred.  I have 
to replace the filament in the 602E and have used up all the old spares so 
must order some more.

Thanks
Kim
