The circuit in Fig 1 is based on a small RIAA preamplifier PCB called the "Lenco VV7", which was intended for upgrading systems to use MM cartridges where the amplifier had only a ceramic pick-up input. It was a Swiss product distributed in Britain by Goldring.

Phono Preamp Design Using Active RIAA Equalization Introduction. This page contains equations and a procedure for accurately computing the circuit component values for a phono preamp using active RIAA equalization. The circuit to be discussed is shown in Figure 1 below.

The preamp is designed for moving magnet (MM) and high output moving coil (MC) cartridges with a signal level over 2.0 mV. I believe the best way to handle the output from a low output MC cartridge is with a transformer so no attempt was made to handle them with this project.

Design Considerations - Op-amp based Phono Preamp The circuit is a non-inverting IC based filter with significant gain. Four of the components in the feedback loop determine the proper RIAA compensation. Slight variation in any of them is unlikely to be audible.

RIAA equalization is a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America (RIAA). The purposes of the equalization are to permit greater recording times (by decreasing the mean width of each groove), to improve sound quality, and to reduce the groove damage that would otherwise arise during playback.

A phono preamp is an outboard device that steps into that void, boosting a turntable’s output so modern electronics can play it at the proper volume level while adding equalization standardized by...

This tube phono preamp provides a smooth sound quality with RIAA equalization. You can enjoy the most realistic sound effects with the help of this phono preamp. Features. This phono preamp features RIAA equalization for noise-free sound; The output power of this preamp is around 0.5 Volts.
