Super-premium Octal Beam Tetrode, impervious to overload when used at parameters found in existing 6550/KT88/KT90 circuits. Plate dissipation of 60 watts and higher current handling capacity has allowed the design of new amplifiers which are unique, extremely powerful and stable.

  • Delivers peak power with extreme reliability and long tube life
  • A pair of KT120s in push-pull configuration can deliver power levels of 150 or more watts
