Hi Nolan:
I just saw the pics of your Zenith collection in the wall unit. Nice!
I think I saw a pic of something like that here at AK some time ago which was built for a TV collection, but I can't remember off the top of my head who had it.
I've managed to squeeze most of my own small Zenith radio collection into my bedroom, with the exception of my K731 which is atop the refrigerator in the main part of my apartment (being a one-bedroom unit there isn't much room). One of these days I'll get around to taking a picture or two of my collection.
My Zenith collection thus far:
H-511Y (1951)
Royal 1000-1 T/O (1958)
K-731 (1963)
R-70 AM/FM portable (1980)
H-480 AM/FM/FM-stereo clock radio (1980)
C-845 (1960)
