   are you looking for a design to build?  single-ended triode config?   
      
   I think you would be better with a push-pull triode config if you want   
   triode final stage.  And I'd suggest sticking with the reference designs   
   when possible.  You should be able to find some online... maybe for a   
   different output tube but then you make little tweeks here and there for   
   output impedence and bias and whatnot, and voila!   
      
   also consider that when an output transformer voltage swings positive on   
   the plate, you can nearly double B+ voltge at the plate.   
      
   Or were you actually looking at a resistive plate load?  (not recommended).   
      
   You can get inexpensive output transformers from guitar repair parts   
   places online - I think 'amplifiedparts.com" is one of them.
