Langhorn Super
#1

I just found a set of Langhorn (Portland OR) IF transformers. Not a whole radio but parts from a very obscure manufacture of interest in particular to those of us in the Northwest. There is at least one picture of an assembled radio on the net:

I would be interested in hearing of any other radios by this manufacture. Also the very remote possibility of finding enough parts to assemble a complete receiver.

  AS you well know RCA had a firm lock on the superheterodyne patent, so the majority of non RCA superhets from the 1920s were either home brewed or sold as kits. Apparently there was a loophole created by a judge that allowed people to built their own or the sale of kits for "experimental purposes", but it wasn't clear exactly what level of assembly constituted a "Kit". The radio linked to definitely had Langhorn branded IF transformers inside, but I also noticed that it had General Radio made tuning caps, the front panel doesn't seem to have a brand name engraved in it (though it looks like the Leutz superhets didn't either) only knob functions. Did Langhorn manufacture this radio in whole? Was it a kit they manufactured? Or was it a nicely made home brew where the builder selected Langhorn IF transformers? In any event if you can identify the manufacturers of the other parts used in this set, assuming it was a factory built or kit set made by Langhorn, you could probably make your own, the front panel will be the hardest part to acquire even as a blank.

Arran,

Yes, I assumed this was a kit. In most cases I have no interest in homemade radios. The 1920s supers are an exception.

I was hoping to find some information to get me started in collecting parts. Other than the single unit (above) and one mentioned on ARF, there seems to be nothing. What I need is a schematic and/or parts list. A sales drawing could also help. If I do try to recreate a Langhorn super, I would like it to conform to the original kit specs.

  That sounds like an interesting research project, hopefully whomever posted the page you linked to finishes putting it together as he has with the other pages, and lists whatever parts were used in his set.

Arran
