about this tube 
     The auction is for one tube.  They can be closely matched and tested for noise.      
    
      (6V6GT)

Beam power tube 6P6P series glass crust eight GT's anticathode limit dissipation power is 12W, can be used to amplify A1,AB1's power.
6P6P is the same with 6V6-GT, and can be exchanged each other.
