   Hey. Thanks for the answer. I.m pretty much aware by You recommendation but   
   this is what I have on my shelves. A kt120  matched quad, a hefty power   
   transformer able to provide B+ 600v/1.5A and a Hammond 1650R 5k Ra-a. And I   
   wonder if such of load is able    
   to provide decent results for a push pull project with 4xKt120 in triode mode   
   please. Thanks.
