A phono preamplifier's primary task is to provide gain (usually 30 to 40 dB at 1 kHz) and accurate amplitude and phase equalization to the signal from a moving magnet or a moving coil cartridge. In addition to the amplification and equalization functions, the phono preamp must not add significant noise or distortion to the signal from the cartridge.

MM-Phono Pre-amp Circuit. Update 14-Mar-2021: The BF862, BF245C and BC560C are discontinued, but there are possible substitutes. ... but the low 150R impedance at that point makes its effect insignificant in the audio band, and it only rolls off the open-loop gain above 50kHz. The much smaller 68p starts its effect at a lower frequency, but the ...

Phono Pre-amp Design. Phono Pre-amp Design Theory. There are plenty of perfectly good moving-magnet phono RIAA pre-amp circuits published, and I was originally planning to just copy a simple op-amp based version, but I decided to be a bit more adventurous. There are well known but rarely used methods both for noise reduction and rumble ...
