It's for using your radios amplifier/controls/speaker(s) to play back
the signal from an external Tape/Phono player.

5 pin din on rear panel marked tape/phono. Is this a tape output and phono
input? Anyone got a pinout? Is the pushbutton selector marked with a circle
and line to listen to phono input? Is this high or low level input? Is
there a better newsgroup to post these questions? Am I even close?
