  How a differential amplifier works is one tube section is forced to do the opposite of the other due to the cathodes being coupled together.
  
  As 'phase splitters' go its a pretty elegant approach and does not have the sonic signature associated with most other phase splitter circuits. If you were to drive each half of the differential amplifier with your transformer the result will be lower distortion than if you drove the 6SN7 sections each single-ended.

    Did you check out the schematic of the amp i will be copying? The amplifier section will be proceeded by a Lundahl phase splitting input transformer. In my amp i will be using a 6sn7 or 6sl7 for the driver tube. I don't think you can get it any simpler or more efficient than that. cheers, Dak

      Set up the way you are describing probably not. I could draw something up though.
