Antique radio links please

The most comprehensive site for FM-only radios is the site belonging to Andrew Mitz:

http://www.somerset.net/arm/fm_only.html

Another good one with a number of pictures and restoration stories is

http://www.sparkbench.com/

He has a homebrew section linked on his first page that shows restored 1920's stuff such as an Ultradyne (and he shows the same schematic as mine).

And for all of us who collect Philco:
