Genuine all tube design

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 tickness
