Vacuum Mono Tube Power Amplifier

Pure Class A Technology

  • Solid aluminium chassis – leads to the overall robustness and eliminates the vibrations
  • Supersymmetric design – eliminates interfering signals
  • Extremely low harmonic distortion – one of the best ever seen in vacuum tube amps
  • The transformer core is vacuum impregnated, and the entire transformer is encapsulated in a special anti-vibration compound
  • The filtration capacity is 3.900mF/550V. A choke, that is placed under welded cover, has been used to eliminate anode voltage ripple
  • The output permalloy transformers specially designed for the power amplifier.
  • Only high-quality polypropylene capacitors are used in the signal path
  • The conductors on the signal paths consist of slow drawn oxygen-free copper, which is coated with pure silver.
