If the phono cartridge is a ceramic the intrinsic characteristics actually equalize the RIAA curve very well. A magnetic cartridge will require equalization but since the output is in the 10's of millivolts range it will also need about 40db of amplification to take it to the ceramic output levels. So you would need a preamp to use a magnetic cartridge with an old radio which most likely will have built in RIAA equalization.
