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).
