You might have an old Dual, Lenco, Thorens turntable, ... now is the time to bring it back to life with a guarantee of quality.
The diagram shown is taken from an old AN-124 application note from PMI Analog Devices around SSM2015. The latter being obsolete, I used a THAT1510.
The peculiarity of this assembly lies first in a pre-amplification before attacking the RIAA filter. Usually, a lot of PAs are built around a single operational amp (NE5534). As the noise level of the That 1510 is significantly lower, you will notice the difference. It will always be possible to modify the gain with the formula G = 1 + 10K / Rg
 Each cell has its attributes and the level is sometimes very different. If one wants at That 1510, the gain resistance can be replaced by a fixed 100 ohm resistor in series with an adjustable 220 ohm. The gain will be variable from 30 to 40 dB.
The NE5532 of the filter and the output stage can be replaced by LM4562
