PRO-JECT TUBE BOX SE II MM - MC PHONO PREAMPLIFIER

Pro-Ject's Sleek Tube Box SE II - Mmm...Tubes.

Using a pair of 12AX7s for the output, the Tube Box SE II is housed in a special metal casing to protect the delicate phono signal from EMI/RFI and provides protection from vibration. The circuitry has been optimized with a shorter signal path, and is now laid out in a true dual-mono configuration. Multiple selectable impedance settings are provided for both moving magnet and moving coil cartridges. A defeatable subsonic filter helps eliminate unwanted low frequency rumble. The Tube Box SE II delivers the magical warmth and richness that only tubes can deliver.
