Audio Research PH6 Phono Preamplifier, silver finish

The PH6 is a hybrid phono stage with a low-noise, high-gain JFET input stage with constant current stabilization and no overall feedback. Unlike its predecessors, the PH6 incorporates two high current 6H30 twin triodes in the gain and output stages; you can expect over 4,000 hours from the PH6’s tube set. Total gain is 58dB, more than sufficient for low output moving coil cartridges when it is partnered with an appropriate line stage. Bandwidth is an incredible <0.5Hz to 400kHz (-3dB).



About This Product

Fantastic condition trade-in Audio Research PH6 Phono Preamplifier in Silver finish.

Unit comes in original box with owners manual, remote, and power cord.

Unit is rated 8/10 for very minor cosmetic wear consistent with age and use.
