  1. I have a trashed portable tape recorder that I rescued from the junk
    bin at an estate sale. I'm looking for manuals, schematics, any
    information I can find about this thing at all--I haven't been able to
    find anyone in portland who's interested in even looking at it to see
    what's wrong with it. It's a solid machine, it has multiple inputs and
    outputs, adjustable recording levels for each channel--it seems like
    if it were repaired, it would make a super durable portable tape
    player. the model number is CD-330. I'm guessing it was made 25-30
    years ago, just by the looks of it, the brand is Superscope, but it
    notes on the label: 'designed by Marantz, USA.' Thanks--Alex

    It has been many years since I have serviced these, to the point that it is
    hard for me to remember much. But, what I can recall is that I had to
    change capacitors in these that went high in ESR. This was more of the
    faults than anything else, as long as the mechanics were good. As for the
    factory parts, they will be almost impossible to have, unless you can find
    another scrapper like yours.

    I found a schematic on microfiche in my collection if you have any specific
