Phono step-up preamplifier for MC cartridge
The MC AMP (vpp02 )
The MC-AMP is a step up units with tube amplifier that operate on class A. This preamplifier make as adaptor amplifier ( +22db) for MC cartridge so you can use your moving coil directly to moving magnet input. The circuity use only two tubes as ECC 88/6922 selecting at very low noise operation . It's possible to change the input resistance of MC cartridge by external RCA- resistor plug for to have better interface between cartridge and input tube.
We supply four pair off plug-resistor set as per value off: 30 ohm (Blu plug) 100 ohm (Black plug) 470 ohm (Green plug) and 1000 ohm (Yellow plug). With this PLUG-RESISTOR you can optimize the resistance value of your MC cartridge.
The exceptional signal to noise ratio togheter a hi-gain operation allow to overtaking the limitation of transformer step-up (distorsion and frequency response limits).
- Cherry wood veenerede for lateral side panels (optional)
- Separate power supply unit (series)
- Low noise selected tubes as 6922 ( 2 unit series)
- Hi-shielded metal frame chassis
- Two power supply toroidal transformer
- Cathode controlled circuit for reducing the noise ground (special circuit patended by Lector)
- Black ash plexiglass front panel as 8 mm thickness
Phono riaa preamplifier for MM cartridge
The Phono-MMP
Genuine all tube design
The Phono M M P is a complete phono riaa all tubes preamplifier that operate on class A without any local or total feedback circuity. This preamplifier provide the right amplification and equalization to standard riaa at the phono moving magnet cartridge signal. The circuity use three tubes, two ECC-81/12AT7 for moving magnet input (as passive riaa equalization) and one ECC-81/12AT7 for output as cathode follower adaptor, all tubes are accurate selected at very low noise operation . A innovative circuity designed from enginner of Lector make the control of the bias by optical devices for clear sound and phase control. A solid shielded cabinet as hi-tickness off 1,5 mm reduce interference from emc field for a better signal to noise ratio.
For to built this riaa phono preamplifier we have design the circuit with minimun capacitors on signal path (only 2 as polypropilene grade) hi-reserved energy power supply with capacitors filter located near to active device.
- Cherry wood veenerede for lateral side panels (optional)
- Low noise selected tubes as 12AT7 (3 unit as series)
- Hi-shielded metal frame chassis
- Hi-quality toroidal power supply transformer
- Cathode opto circuit for 12AT7 riaa moving magnet
- Black ash "piano finish" plexiglass front panel as 8 mm tickness
- passive riaa equalization by precision components
PHONO AMP SYSTEM
This phono stage is a pure tube unit that offers both MM and MC inputs. It operates only in pure class-A without any local or total feedback circuitry, and provides the exact right amplification and equalization to the RIAA standard for both moving magnet and moving coil cartridges. The circuitry uses five ECC-88/6922 tubes for moving coil operation and two ECC-81/12AT7 for moving magnet (as passive RIAA equalization), and one ECC-81/12AT7 for output as a cathode follower adaptor. All tubes are carefully selected for exceptionally low-noise operation. All connectors are high-quality RCA fittings.
An innovative bit of Lector-designed circuitry automatically adjusts the control of the tubes’ bias by optical devices, and another bit of special circuitry controls the cathode operation for very low noise in the moving coil input. You can change the input loading of MC cartridges by use of external RCA plugs fitted with specific resistors for a better interface between cartridge and input tube. 47 Kohms is the default loading, and Lector supplies four other pairs of plug-resistor sets: 30 ohms (Blue plug), 100 ohms (Black plug), 470 ohms (Green plug), and 1000 ohms (Yellow plug). Its exceptional signal to noise ratio, together with its hi-gain operation, allows the Lector Phono Amp System to overcome the limitations of transformer step-up (possible distortion and frequency response limits, as well as the inability to properly load MC cartridges) and deliver pure tube-amplified music.

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
