I recently purchased a vintage Magnavox stereo 1P4125 [280 amps/117v/60hz], with AM/FM radio, 3 speed reel-to-reel tape recorder and a 4 speed record player. All the equipment works well.
Now I want to hook up a 5 disc CD player and I removed the back fiberboard panel and found the Auxilary panel which looks like this: two plug-in inputs on top labeled, "Line Output" with purple wire "right" and yellow wire "left" and the two plugin inputs below that are labeled, "Aux Input" with purple wire "right" and yellow wire "left". I disconnected the Aux Input purple and yellow wires which I assume go to the tape machine and pluged in the right [red] and left [black]channel wire from the CD player. I left the top "right" and "left" wires in place. I also disconnected the tape deck electrical plug and pluged in the CD player plug in its place.
I turned the radio on,l turned the knob to Tape and turned the CD player on. All the lights lite up and the CD played, but I got no sound.
What am I doing wrong? Can anyone help me figure this out? Thank you.
