Its possible to create simple RIAA pre amp using the gate of the logic circuit type CD4069. Look at the schematic diagram above. Note : The Power supply must be single, between 3 V and 15 V. In practice, a voltage of 2V is also sufficient for the voltage drop of logic gates is much lower than that of the op amp.
