7566 Overview
The 7566 is a Phono preamplier intended for Moving Magnet and Moving Coil cartridge signals. It features purpose-designed low-
noise discrete JFET input Class A ampliers throughout the signal path, a passive RIAA lter with low-tolerance components and an
oponal 18dB/octave Rumble Filter with a corner frequency at 11.4Hz.
