Stereo Phono Valve preamplifier
The original Phono One phono stage was one of the most admired and beloved products in Unison Research history. When production was discontinued some years ago, the requests for a replacement never ceased. For that reason, we decided to improve and reintroduce this design.

We retained the exterior appearance of the original since we have always considered this design to be timeless, its aesthetic appeal is still undiminished and best left untouched. While the circuit used in the Phono One has many features in common with the more affordable Simply Phono, one more valve has been added, bringing the number of triodes (i.e. five ECC83/12AX7 double triodes) up to ten.
