many stereo systems come without the phono preamp. Connecting a 
turntable to such a system requires a separate phono preamp (starting 
around USD 100 for an entry-level device).

audio input to the stereo's output (where you connect the tape 
recorder). In fact, you could connect your Mac to the stereo chain 
instead of a tape recorder.
