  3. It could be almost anything. Do you have a picture of it?

    I worked for Radio Shack back in the mid '70s and I remember the tubes being made by several manufacturers including Sylvania, RCA and GE.

    If I had it, I could probably tell you what it is.

    There were various code systems that could tell you a lot about the origins of any mystery tube, but they have to still be there and legible.

    Alternately, you can recognize the internal structures of a lot of typical tubes as being from certain manufacturers.

    As has been pointed out, there were many, many suppliers of tubes to Radio Shack. Could be anything.
