Replacement Valves

The Pro-Ject Tube Boxes use valve technology in the pre-amplification process to add a warmer, more musical tone to the eventual sound output. These valves are replacement pieces - please consult a recognised service engineer before doing any work yourself.

The Tube Box S/E II and DS use the same valves as the smaller Tube Box II and Tube Box S models; however, the bigger versions also have an extra cool-daming casing developed by EAT - like a spiders web - that helps diffuse heat and reduce movement of the valve in situ.

The valve model number is ECC83 (12AX 7A), but is marked with a Pro-Ject logo.
