   probably because it was designed specifically FOR that (vertical    
   amplifier/oscillator in a TV, requires large linear region for wide    
   plate voltage swing)    
      
   makes sense to me.  I'll consider this tube as a driver for beam power    
   tubes in the future.    
      
   Its good, even if you can't make any sense of this now.   
   McIntosh reckoned they were just right in their amps.   
      
   Tubes were rarely ever limited to ONE purpose the designers may have had in   
   mind.    
      
   And I still make gear just to fill in time, no particular purpose at all, and   
   last month I got an RF gene going real well, with AM and FM, and I used tubes   
   which seem quite out of place, such as 6CW5/EL86 for a triode concertina phase   
   splitter & buffer    
   for RF up to 2MHz. Worked better than 12AU7 and other tubes I tried.   
   Sometimes, if you think outside the square, you look back at the square, and   
   you see its a circle.......
