Stereo fet/bipolar hi-current integrated amplifier

Stereo tube line level preamplifier with 5 inputs,2 main outputs, passive volume out, tape out, htd output
Z A X  design amplifier line include two models, the ZAX-60 at 60 watt per channel at 8 ohm, and ZAX-120 at 120 watt per channel at 8 ohm.

ZAX design project is a hi-advanced technology in new era of amplifier with new concept as intended amplifier as drive any SPEAKERS charge in any condition of input signal! ZAX design project is based on hi-voltage circuit (120Volt DC) and Hi-current circuit (+/-20amp PP). For  reach this ambitious design our engineer ask to suppliers special components as:

  • Special transistors with hi-current and hi voltage can be handle little signal (first watt control)
  • Special output device transistor can handle hi-current with special built-in temperature compensated
  • Special power ac main transformer with hi-energy and low leackege lost flux

The ZAX produce outstanding sound quality: the FET stage give a sweet and smooth soundstage and otherwise the hi-energy power output transistor produce right performance for detailed high frequency and beatifull bass response with authoritative control. The electronics circuit is based on all soslid state device as transistor and fet (input device) non any I-C chip integrated circuit is on the signal path! (The IC cannot delivery hi current!) The amplifier has 5 five hi-level line inputs  and a pair of speakers system output and a tape record output.

VF1-70L remote hybrid integrated - £1000

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...

• 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

VM-200 HYBRID POWER AMPLIFIER

Stereo hybrid (tube/mosfet) power amplifier

Lector proudly introduces the all new VM200 hybrid power amplifier featuring an innovative direct coupled circuit from tube to mosfet. No any coupled capacitors is on signal path!
This new concept offers a transparent and rich dinamics sounds performance.

A lot of new innovative technologies and solution has this power amplifier rathed as 100 w per channel:

  • only two stages from input to output (first stage by triode and second stage by pentode)
  • dc coupled design from tube to mosfet without any capacitors!
  • triode / pentode tube driving the mosfet  in pure class A
  • low feedback design set to only at 10% db

The power supply employ four stages  and  two  toroidal power supply : shunt regulator for tube , hi-energy reservor capacitors for output mosfet, also the tube-filaments are supply on d.c. for lowest noise floor ! The electronics and mechanical parts  are selected as  all premium grade components : polypropylene capacitors, toroidal hi-energy power transformer (2) , metal foil and tantalium resistors, 1.5 mm tickness steel chassis box, 8 mm tickness plexiglass front panel.
For better quality sound reproduction the output device don't use any type of protection  as limiting the current so itís possible to drive low impedance loudspeakers with very good stability and energy power reservor . VM-200 : smooth musical and true natural reproduction.

Phono riaa preamp amplifierier for MM cartridge
Phono riaa preamplifier for MC cartridge

All solid state design

The  preamplifier MM 70 mm  is a complete phono moving magnet/moving coil riaa all solid state design that operate on class A . This preamplifier provide right amplification and equalization to standard riaa at the phono moving magnet/moving coil signal. The circuity use a discrete device for moving magnet input, the active device has beed  selected at very low noise operation . For best clear sound just a one output capacitor as polipropylene audio grade is include in output circuity. A solid shielded cabinet as hi-tickness off 1,5 mm reduce interference from emc field for a better signal to noise ratio.

Great attention by designer has beed look around the power supply, this circuity operates with over ten-thousand microfarad capacitors for reduce the noise and best reseivor energy, this hi value capacitors works togheter with a special ultra low noise voltage regulator devices
