LFD AUDIO: Q/A with Dr. Bews. Specifications of vintage MC1 and MC2 phonostages

Phonostage MC1 and MC2 have been designed as dedicated RIAA equalisation stages for Moving Coil cartridges only. A separate power supply enclosure is employed to reduce hum pick up from mains transformers and provides a greater degree of flexibility in positioning.

A low output impedance allows even long Interconnect cables to be used. Both phonostages use similar topologies, but the MC2 utilises custom made passives and a floating input bias scheme similar to the State-of-the-art Battery Disc preamplifier.
