The PH9 phono corrector is an excellent solution for matching most cartridge and player combinations to your system. The 6H30 vacuum tube trio is at the heart of a simple and clear signal path to ensure the most transparent pre-amplification.
Audio Research Reference Phono 3 SE is a tube phono corrector. Phono 3SE has a design developed from scratch, absorbing the successful findings from Reference Phono 2. In fact, the Reference Phono 3SE is a synthesis of developments from the entire Reference series. An additional gain stage allows you to obtain the linearity of gain characteristic of the Reference 10 and Reference 6 preamp models.
Tube-based (6 x 6H30P dual triodes, plus 6550WE and 6H30P in power supply( phonostage with selectable loads (1000, 500, 200, 100, 50 Ohms) and maximum balanced output capability of 30V RMS.
