REFERENCE PHONO 10 PHONO PREAMPLIFIER Vinyl record playback has been an integral part of Audio Research since our founding in 1970. Think back to the great phono stages built into the defining preamplifiers of their day, among them the SP3, SP6, SP8, SP10, and SP11. Even after the introduction of the compact disc in 1982, phono sections remained a revered part of our preamplifiers. The firs...[more]

he heart of the Revelation 2 Phono is a classic RIAA EQ circuit that’s won raves from countless audiophiles and reviewers. We paired this musically refined circuit with an output stage based on the fully balanced Line Stage Gain Modules found in our award-winning line stage preamps, using hand-matched transistors selected for their outstand­ing, ultra-low-noise performance. The Re...[more]

The LP1 has 47dB of gain, perfect for higher output (>1.0mV) phono cartridges. It is a hybrid design utilizing one 6H30 tube, special low noise JFETs, custom Audio Research designed power transformer (made in the U.S.), and multiple stages of regulation. There is no overall feedback, and it is non-inverting.  Inputs and outputs are single-ended. Controls are as simple with switches for Pow...[more]

The choices of the load are 47K, 1000, 500, 200 or 100 ohms. All functions are duplicated on the remote control. The rear panel includes a pair of single-ended inputs, a ground, and a 15A IEC connector. The PH6 is a hybrid (like PH5), with high-gain JFET input constant current and stadiuo stabilization without any counter-reaction. The PH6 uses four 6H30 twin triodes. Instead of replacin...[more]

The PH7 has 57.5 dB of overall gain, and features one pair of single-ended inputs and outputs. Full remote control is provided for all functions, coupled to an easily readable front-panel vacuum-fluorescent display. The display shows all selected functions including loading (47K, 1K, 500, 200, 100 ohms), as well as accumulated hours of operation. Display intensity can be adjusted to one of eight l...[more]
