The Pro-Ject Tube Box SE II is a cost effective way to achieve audiophile-quality amplification and RIAA equalization, using a pair of ECC83 / 12AX7 triode tubes for moving coil or moving magnet phono cartridges with up to 60dB gain (MC). The robust metal case shields the internal electronics from both vibration and electromagnetic interference while providing a compact layout space for the discrete dual-mono circuitry. Multiple selectable impedance settings are provided for both moving coil and moving magnet cartridge optimization. A subsonic filter provides attenuation of low frequency noise and rumble. An outboard power supply is included to minimize unwanted noise.
