  • Tape deck?

    Is it possible to modify a tape deck as to have audio-in?
    I have an old deck, and don't want to have to buy a new one.
    Thanks

    Yeah, you should be able to, but you will probably have to cut through the tracks, or remove the tape from a tape, and put that in when you want to use the player. To modify the tape player, just tap into the volume control pot.

      See AndyM's site

      he did it.

      In this post he said he was going to take some pics of the mod and post them.

        I did this with an old minisystem i had so i could connect it to an alarm clock. i cut the wires from the tape head and spliced them to a old head phone jack (red was right,white was left and black was ground). Should be that easy.

        On the alarm clock side i removed the spearker and hooked on a source level adjuster to drop the strengh of the signal down to the strengh of a tape.

        I imagine you could forget about the level adjuster and just turn your sound card way down.
        Hope this helps.

          If you cut the wires to the tape head, you will have to use a voltage divider to bring the signal way down as to not overload the very sensitive preamp. It will probably not damage the preamp, but would cause horrible distortion.

            Aaren it depends where is he going to hack in to.
            There is not much point getting a line in before the tape_heads preamp.
            There is usually another preamp after the tape_heads preamp and that where you need to hack in to.
            If you got a scope you can check the level output and will tell you if its the right line.

              So, since I have 3 in on (AM/FM,CD,Tape) I could essentially use my tape deck as an AUX IN???
              I would of course have to open it up and jimmy it a bit, right? What would I look for?

                If i had the choice between Tape/CD/FM lines
                then first i would choose CD then FM and only then TAPE lines.
                Usually there is a cap/resistor bridge on those lines going to the preamp and different sound sources use different value.
                And the CD line would be most appropriate for what we needed it for.

                  Indeed. I went for the FM line when I modded my head unit for aux in. I kept the radio working and switch over using some lines from the parallel port when I play MP3s. Works just great. Details are on my homepage.

                    I went there and couldn't figure out what you were saying. I'm a newbie. Would you have the time to explain it to me? sounds like a good way to do it.

                      The circuit diagram for the exact mod I made is on my website. The basic gist of it is that I used a relay to switch the FM input to the stereo processor between the FM decoder and the output of my mp3 player, using some lines of the parallel port to switch the relay.
