   ** FFS  -  just add 2 ohms to the 38 ohm winding.   
      
    Problem gone.   
      
    Dodgy 5U4s etc not withstanding.   
      
    SET amp loonies sure are a bunch of neurotic old women.   
      
      
   I'm not so sure an added 2r to a winding with 38r would fix the "problem".   
      
   ** Who cares about that.   
      
      
   What if there is slight difference in turns of the CT winding?   
      
   ** Not at all common and not mentioned in the OP.   
      
   What if there is Idc imbalance in the two output tubes?   
      
   ** Huh ??   
      
   Got nothing to do with the issue of 50Hz PSU ripple.
