Well, your 3808 has a phono input, so......
They had some models with a set of jacks labeled 'Phono', but I think they expected people to use a phono preamp because not many were actually using a turntable at the time and those who might need additional inputs couldn't use the Phono jacks because it's not easy to reverse the gain and RIAA equalization. I don't remember which models had a phono input, which didn't or which had it labeled as that, without a phono stage.
