Pro-Ject Tube Box E Tube Phono Preamplifier

Compact tube-based phono preamplifier with fully discrete circuitry and replaceable ECC83 tubes — designed to bring warm, musical analog sound to your turntable setup.

The Pro-Ject Tube Box E is a precision-engineered tube phono preamplifier that enriches your vinyl playback with the classic warmth and musicality associated with tube amplification. Its fully discrete circuit design avoids operational amplifiers for ultra-low noise performance and accurate RIAA equalization, resulting in clean, natural sound with lush mids — typically found in much larger and more expensive tube phono stages. Supporting both moving magnet (MM) and moving coil (MC) cartridges, Tube Box E features adjustable gain and loading options to match a wide range of cartridges. The front-panel subsonic filter and gain controls let you tailor performance on the fly, while replaceable 2 x ECC83 tubes offer the freedom to experiment with tube rolling and fine-tune your sound signature. Built in a rigid metal enclosure with beautifully machined aluminium controls and gold-plated RCA connectors, Tube Box E offers both reliability and elegance — available in classic black or silver finishes to fit any hi-fi system.
