DetailsHoused in a sturdy metal case, the Project Tube Box SE II features two double triode valves to provide the amplification for the phono signal from either MM or MC cartridges. Loading impedance and resistance for MC and MM cartridges respectively can be set to suit the specific model of cartridge in use, which results in a more more balanced sound reproduction. A switchable subsonic filter removes excessive cone movement from you loudspeaker when playing warped records. Gold plated RCA input and output sockets allow you to connect up using your favourite interconnects, whilst the external power supply ensures noise and hum is minimised.
