About the PH 9.0X
The ModWright Instruments PH 9.0X is a two-chassis, all-tube MM/MC phono preamplifier derived from the PH 9.0. Its distinguishing upgrade is a pair of Lundahl LL1660S gapped output transformers, which replace output chokes and coupling capacitors in the signal path, provide fully balanced XLR operation, increase maximum gain by 6 dB over the standard PH 9.0, and offer very low output impedance. It has separate RCA inputs for MM and MC cartridges, selectable MC resistance loading, adjustable gain attenuation, stereo/mono switching, and an external solid-state power supply. The PH 9.0X is documented as an available model and is not identified as discontinued.
