DetailsThe Project Tube Box II is a dual triode valve MM/ MC phono stage of great quality and outstanding sound quality. Constructed with a dual mono circuit design for best channel separation, having switchable gains to suit both moving magnet and moving coil cartridges and a slectable subsonic filter to reduce the effects of warped records on your loudspeaker cones. Full RIAA equalisation is accurately applied to the signal, whilst gold plated RCA phono sockets ensure a trouble free connection. An external power supply minimises noise and hum pickup. Metal casework shields the delicate phono signals to ensure that it delivers crystal clear sound quality to your amplifier.
