TU-8340VK Push-Pull Amplifier Kit   
■Semi-Automatic Bias Adjustment- Adjust the bias by simply pushing a button!
■Supports various output tubes
   Semi-auto bias adjustment supports 6L6GC series (KT66,etc), KT88 series (6551,
   KT90,etc),as well as the default EL34 series (6CA7, KT77, etc) tubes.
   The robust transformer can support tubes with higher heater current requirements  
   such as the KT88 series including the KT120 and KT150.
■ 2 types of amplifier modes - Switch between Ultra Linear and Triode.
■ Enough space for upgrading to large coupling capacitors if desired.
■ Universal power transformer supports 100V, 115V, 200V and 230V
