ModWright PH9.0 MM/MC Phonostage Specifications
The PH 9.0 uses the same (2) 6C45 and (2) 6922 tube complement and embodies the same tonality,
soundstage and musical presentation of the reference line. Max MC and MM gain of 64dB and 52dB
respectively, as well as 0dB, -6dB and -12dB gain adjustment, accommodate a broad range of MM
and MC cartridgesThe back panel features one set each, MM and MC RCA inputs and one set of RCA main outs as
well as optional (additional cost) fully balanced, transformer coupled XLR main outs. Turntables with
two tone arms are easily accommodated, and with an outboard step-up transformer for the MM input,
two MC cartridges may also be used.
Dimensions: 10”L x 10”W x 4”H (phono); 9”L x 7”W x 3”H (power supply).
PH-9.0X Model:
What the PH 9.0X upgrade includes:
The upgrade to the PH 9.0X involves the addition of a pair of Lundahl gapped output transformers, commonly used in SET tube amps. The addition of these transformers also means the elimination of a pair of chokes and coupling caps, all in the signal path.
Why this upgrade?:
The circuit change made to the PH 9.0X, make it much closer to the PH 150 in terms of overall circuit design. Various other circuit differences in the PH 9.0 vs. the PH 150 were implemented, to see where the PH 9.0 could be improved. Most either made no difference, or for whatever reason, did not sound as good in the PH 9.0. This circuit change however DOES make a difference. The use of the Lundahl output transformers was one of the cost cutting design changes made to the PH 150 to achieve the PH 9.0. I found that the improvements were simply big enough that it warranted offering the upgrade, as an add cost option for the PH 9.0.
Sonic Benefits:
The sonic benefits of this circuit change are obvious and significant! There is better bottom end, more weight and authority to the sound as well as improved resolution, detail and soundstage.
