This tube triode mosfet integrated amplifier use the same philosophie of our combo PRE/POWER VP04/VM150 :
preamplification for phono and line by triode
output stage by hexfets ( special mosfet )
only local feedback for output stage, no-feedback design for tube preamplifier section

The phono stage is based on this solution:
air of tubes ECC 81/12AT7 for phono amplifierdouble triode ECC 82/12AU7 for line/cd inputs

• passive riaa stage with accurate components @ .5 % tollerance

A lot of new and original electronic architecture have the circuity of VFI70:

• optical bias control on triode
• absolutle zero feedback on tube section
• very low feedback on Mosfets section
• only three polipropilene capacitors on signal path

As all our realization the components are only premium grade.
Sophisticated power supply circuity with four independent section:
power mosfets, filaments, anode plate, phono stage.
The class of sound of the VFI 70 can compare also with most important solid state Pre/Power combo probaly the VFI 70 sound better: more transparent, detailed and better soundstage.

CONVENIENCE AND PERFORMANCE

• Internal output stage attenuators for better fine tuning sensibility.
• Hi - quality potentiometer as audio premium grade
• Version VFI-70mc comes in two boxes (separate power supply model PSU-70)
• Cherry wood veenering for lateral sides (optional)
• Motorized potentiometer with remote control handset (optional)
