Accuphase C-220 (type A) Stereo Disc Equalizer Phono Preamplifier

Rare Accuphase C-220 Stereo Disc Equalizer from the golden age of audio for superior vinyl playback. This phono preamp features both an equalizer amp and moving coil head amp, as well as a flat amp with volume control for direct connection to a power amplifier.

The head amplifier for MC cartridges is built in and, in 26dB and from an equalizer to an output, head amplifier is giving a gain of 60dB. Moreover, head amplifier was changed by relay control, by electronic, a muting relay and time lag of the output were given and the shocking noise is canceled so that proper use of MC and MM can be performed with one arm.

The input unit of the equalizer amplifier part is taken as the input direct connection circuit in the differential amplification circuit combining the FET buffer. Moreover, pure complimentary connection of the RET which excelled [ output ] in the high frequency characteristic is made, an Output load impedance is lowered by large current drive, and low impedance-ization of NF loop is enabled. Thereby, the input conversion noise of equalizer amplifier has realized -140dBV (2mV of rated inputs, S/N86dB) with the actual measurement.
