Préamplificateur PH8


With the award-winning Reference Phono 2 reigning at the top, and the superb PH6 anchoring our lineup with a more affordable price, we are pleased to introduce the PH8 phono preamplifier. The PH8 benefits from a number of circuit and parts improvements derived from the award-winning REF Phono 2.  Rather than using the four 6922s of its predecessor, the PH8 uses two 6H30 tubes along with special low-noise FETs; vacuum tube regulation incorporates a 6550 and a 6H30, as featured in the REF Phono 2 and REF5.  Capacitors are all the same types as those used in the REF Phono 2, including the same coupling caps, and Teflon® caps used in both the RIAA stage and as bypass caps.  There is also a new R-core transformer.  Circuit board material is the same as in our Reference products.
