Manufacturer's Description:
The Pro-Ject Tube Box II sets the standard for a cost effective high-performance phono stage. This product is built using the same high-grade metal chassis shared with the rest of the Mk II product line. This all metal case features great shielding from both vibration and electromagnetic interference. Selectable MM and MC modes as well as a sub-sonic filter via rear panel mounted switches. Gain is rated at 60dB (MC) and is derived by a pair of ECC83 (12AX7A) tubes.??
