The Phono Amp-System  is a complete phono riaa with all tubes preamplifier that operate on class A without any local or total feedback circuity.  This preamplifier provide the right amplification and equalization to the riaa standard  at the phono moving magnet and moving coil  cartridge signal. The circuity use  five tubes as  ECC 88/6922  for moving coil and two ECC-81/12AT7 for moving magnet (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 engineer of Lector make  the control of the bias by optical devices and a special circuity control the cathode operation at very low noise the moving coil inputs device. 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 (Blue plug) 100 ohm (Black plug) 470 ohm (Green plug) and 1000 ohm (Yellow plug). With this PLUG-RESISTOR you can optimize the right 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).
