Audio Research Reference
The REF Phono stage is an all-vacuum-tube design. Of the 14-tube total, eleven 6922 twin triodes are used in a unique single-ended signal path. High voltage rectification utilizes a 5AR4 / GZ34, while regulation is accomplished using a 6L6GC controlled by another 6922. For the analog music purist, this is the phono stage to make everyone happy! Using chassis construction and dimensions identical to the REF1 and REF2 line stage preamplifiers, the REF Phono makes a perfect companion piece, visually and sonically, to other Audio Research models.
