Virtus M1 • Reference Line

Tube mono power amplifier

 

The pure Class A mono tube power amplifier Virtus M1 serves as a reference power amplifier for CANOR development engineers as well as numerous test magazines and specialist retailers.

Highlights

 

  • Solid aluminium housing eliminates vibrations
  • Supersymmetrical design eliminates interference signals
  • Extremely low harmonic distortion of only 0.0028% at 1 W; 0.011% at 5 W, and 0.13% at 50 W thanks to precise calibration of all circuits and components – one of the best values ever measured in tube amplifiers
  • Vacuum-impregnated transformer core and transformer encapsulated with a special anti-vibration compound
  • Solid welded transformer cover for effective electromagnetic shielding and improved signal-to-noise ratio
  • The filtration capacity is 3,900 µF / 550 V
  • Coil mounted under a welded cover to eliminate anode voltage ripple
  • Output transformers made of MU metal and specially manufactured for this power amplifier
  • Only high-quality polypropylene capacitors in the signal path
  • Signal path conductor tracks made of slow-drawn, oxygen-free copper coated with pure silver
  • Recommended retail price: 14.200,00 €
