So I've deduced that my newly acquired unit does not have the multiplex adaptor that I've read about here.  It will play my tapes in stereo when I have the Tape function pressed along with the stereo button.  It cuts out the sound when I press the stereo button while listening to FM.

I like to listen to FM quite a bit and would like to hear it in stereo if possible.  So...what are these adaptors?  Are they available, or does anyone have one they want to sell?  How difficult is it to install? 

Maybe this should post over in the Workbench forum.
