All solid state design

The  preamplifier M M 70 pp  is a phono moving coil step-up all solid state design that operate on class A . This preamplifier provide right amplification at the phono moving coil signal. The circuity use special  discrete device for moving coil 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.
