Audio Note M3 RIAA Phono Stage
Audio Note M3 RIAA Phono Stage
At the heart of the M3 RIAA is an exceptionally fine Moving Magnet phono stage which uses three 5670 valves. This is followed by a 5687 valve equipped output stage, and both sections are powered by their own dedicated 6X5 valve rectified power supply based on the M10’s Galahad PSU. These power supplies also incorporate an ECL82 for voltage regulation and a 5651 as a voltage stabiliser.
Audio Note copper wiring, a mix of Beyshlag and AN tantalum resistors, SILMIC capacitors and Audio Note copper foil in oil signal capacitors are used throughout the circuit, along with in-house designed and manufactured output transformers which feature I-E M4 cores and copper windings, which facilitate both single ended and balanced outputs. Due to the size of the components used the M3RIAA it is housed in Audio Notes full width chassis, with a choice of brushed silver aluminium or Black fascia.
