| 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.
