  QA-118.jpg  
line stage fully balaced pre-amplifier with interstage transformer and 600 ohm balanced transformer

Use 6SL7 for both the amplification and driver stages for the interstage coupling transformer, and using 6SN7 as the driver stage for the output transformer, there is no coupling capacitor used along the single path which makes this pre-amp a state-of-the-art capacitor-less design. This unit is built with a 5U4G tube rectifier and enhanced power supply which gives you an exceptionally rich, warm, and sweet sounding listening experience.
