Product Information

The ProJect Tube Box MkII phono stage allows you to combine the warm, rich sound of valves with your turntable. This means that you can enjoy a valve sound with your turntable even if you have a solid state amplifier. Its the ideal phono stage if you are finding your turntable is sounding a little harsh through your amplifier or if on the harsh/cold sounding side or if the sound of your turntable is lacking life, the ProJect Tube Box MkII is an ideal choice which should inject some warmth back into the music and remind you what vinyl playback is all about. An excellent sounding phono amplifier, which offers a much warmer sound than the lower model phono amps.

The Tube Box MkII is switchable on the back for use with either moving magnet (MM) or moving coil (MC) cartridges.
