Hybrid Stereo Amplifier. Tube-based input stage, mosfet output stage, fully symmetrical audio path from input to output in push-pull and pure class A. The amplifier has DC protection on the speaker output, delayed speaker activation and remote control including: volume control, balance, changing inputs.

Important features:

  • Overcurrent protection that shuts down the amplifier when the final stage current is exceeded
  • Fuses have been eliminated and electronic protections have been used
  • Volume control without interfering with the audio path (parallel)
  • Silver-copper cabling with MetrumLab technology
  • Minimalist three-stage audio path
  • Only NPN transistors were used


  • Voltage lamps: two PCC88 or ECC88 or 6N6 or 6N30 (per channel)
  • Load impedance: from 4 Ohm
  • Output power: 2 x 50 to 150 W
  • Frequency response: 5 - 30.000 Hz
  • Power consumption: 350 W
  • Weight: 50 kg
  • Dimensions: 42 x 25 x 55 cm
