Cassette deck source/tape monitor switch

So does this mean the monitor switch on the cassette deck wont allow me to compare the source signal (CD) to the signal (tape) being recorded. While I am recording I am trying to compare the CD to the what's being recorded on the tape but I am not hearing a slight hesitation when I switch from source to tape using the monitor switch. Is this because the preamp isnt made to do this.

Thanks

Thanks,

I've been going crazy most of the day trying to figure why the source/tape monitor button didn't work. I am relieved to know that it's not the deck.

Now I can feel more comfortable selling it as I don't want to sell a defective piece.

Thanks Again
