Integrated Hybrid amplifier  mod.  V F I - 7 0L

series 3 (year 2003)

This integrated hybrid amplifier is the line version of our model VFI 70 mm (mm phono input). The VFI 70L-3V  has four line level inputs and one tape output, speakers output is for one system right/left for impedance from 2 to 16 ohms. The VFI 70 is one of the first hybrid amplifier designed in 1982, this clever and realy musical design employ a tube triode in preamplification stages and a hexfet's power transistor in output. The signal path come only into one capacitor selected as MKP polipropilene hi-quality for audio grade selection. This amplifier perform a real impact sound feeling and hi-warm sound with the benefit of tube triode input. Compare the VFI-70L vs.other integrated amplifier no equal sound quality found in the competitors...

OPTIONAL ACCESSORIES AND BASIC DESIGN CRITERIA

• Optical bias control on cathode triode section (patend by Lector)

• Connectors input and output all gold plated

• Double power supply by two separate transformers (toroidal) for tube triode section and power section

• Class A for tube driver without feedback control ( only local feedback)

• Internal hand wire layout  for sensible circuit as power supply,output stages ecc

• Capacitor on signal path made in polipropilene MKP 

• Low feedback ammount on output stages

• Cherry wood veenering sides panel for increse rigidity structure ( optional)

• VFI 70L/M with remote control handset for volume ( optional)

Is possible to order all option as: remote control version+cherry wood
