Yep, I meant 833. It was early in the morning when I wrote that.  I dont 
get up before 9 AM usually.  I have some 866s also for the power supply. 
   Final 4-125s in parallel.  Screen grid modulation.  

I dont use tubes or circuits because they are efficient, I use them 
because they look good.  Some tubes look better than others.  the Eimac 
4-xxxx series of tubes looks better than most.  

The 833 is awesome in the looks category.

813s look great
