Every vintage preamp I ever used had tape input RCA pairs. These RCA pairs were not connected to an internal a head amp, but were line level inputs. The purpose of labelling these line level RCA pairs seems to have been to correspond to the notations on the selector.
A head amp has a similar function to the phono section, (that is, it has to amplify and shape a tiny signal). As such, it is a highly specialized piece, but one which was never close to as common as phono. That is why it was usually part of the tape deck.
