The phono preamplifier PH200 has two low-noise toroidal transformers, one per channel. A steel shell electrically connected to the chassis fully shields the power supplies to avoid parasitic radiation. This shell, as well as the filter capacitors and the chassis, are treated against mechanical vibrations using a specifically adapted material. Operating consumption remains less than 2W. The printed circuit board has a chemical gold nickel finish, which optimizes signal transfer. The masses are routed in a star pattern to ensure perfect power supply noise rejection. 8 mm brushed aluminium front panel. Silver mica technology RIAA filter capacitors. 2 very low noise linear transformers 3,5 VA each. 4 regulated power supplies. Total of capacitors: 54 400 µF. Input impedance: 47 kΩ.
