   You must be looking at the  *SUPPRESSOR*  grid  -  internally connected to   
   the cathode.   
      
   In a power pentode, the screen has to sit in the "shadow" of the control   
   grid or else screen current goes through the roof.   
      
   As it happens, the screen current of the EL84 is particularly low.   
      
   Plus the EL34 and EL84 are very constructed very much alike.
