Here is my favorite radio type item I recently purchased. I think the exposed tubes make it look really nice. This is a Freed Eisemann Broadcast Receiver Model NR-215. It measures approximately 14½” x 17½” and 7 tall to the top surface and 9½” tall with the exposed tubes. I was surprised at how clean it was inside.

I have not found anything like it on the internet.

Anyone know exactly what it was used for.

Thanks,
Trenchartman

    Hello Trenchartman, this is a very beautiful radio and in great shape!

    For what I could understand, this is a MW radio receiver from the 1920's, it is only a receiver, it needs a headphone or speaker connected to it (the transducer).

    It is a Hazeltine Neutrodyne type radio that requires proper alignment of the circuits in order to reach its best performance.

    I could find only this:
    http://www.radiomuseum.org/r/freed_eise_nr215.html

    There's a series of books from Alan Douglas (Radio Manufacturers of the 1920s) that in its volume 2, mentions the history and products made by Freed-Eisemann.

    A nice piece!
