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.
VFI-50 Hybrid Line Integrated Amplifier
- Premiere Tube hybrid integrated amplifier and line dedicated inputs
- Five line input; tube stage as preamplifier, output for speakers system and tape recorder
- Two Big power supply transformers: one as 170 V/A for output stage transistor
- second transformer for tube preamplifier section.
- Only local feedback circuit design :power output stage low level feedback,
- NO any type of feedback on tube preamplifier stage proprietary optical cathode bias invented from Lector Lab's.
- Optional plug-in for remote control handset for motorized pot as volume control
- Optional cherry natural wood veenering for lateral sides
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

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
