Old Sony 250 tape recorder meets my TV

    My tape recorder is probably 30-40 years old. It plays 4-track tapes.
    Twenty or so years ago, I had it tuned up. I recently stumbled onto it
    in a closet and realized that I have some old tapes that I recorded
    family moments on, and it might be wise to convert them to digital.

    I set it up a few weeks ago with a PA amp with speakers I have, and
    found that it more or less worked on a commercially produced tape, 7"
    reel. It was a bit slow, but I could tell music was there. Aside from
    that, when I stop the recorder it makes something of a grunt.

    I did open the top and examine matters, but have no service guide to
    attempt some sort of repair.

    Since the PA amp and speakers are hard to put up for further
    exploration, I thought I'd taking the audio from the recorder to a video
    port on a TV set. I couldn't get any sound at all. Am I missing
    something? Comments?

    What I'm really trying to do is determine whether there is any recording
    on the family tapes I have.

    Mine look as fresh as when I first played them.

    Solved. I was plugging the audio into the wrong ports on the TV. The
    black raised letters around the plugs made it hard to tell what each one
    was. That plus the darkness in the area around the TV.

    There is static when I play any of the tapes. I'm not sure if that's
    coming from the player or the tapes. I don't have any clean tapes.

    It would be good to have a service manual.

    You might want to check this out if you have old tapes.

    I work in video and old 2" tapes almost always require baking to get them to play. At my current and former employers we use a food dehydrator from 125 to 135°F for 8-12 hours for 2" and less time for thinner tapes. This isparticularly useful for tapes 20-40 years old. With the hundreds of tapes I've seen get baked, nearly all were repaired and not one was made worse than it was.
