Here's a neat clearinghouse for our hobby, and a good,
growing alternative to internet auction sites. We now use them
to sell most of our radio-related stuff.
VRPS
is Vintage Radio & Phonograph Society in the Dallas area.
My very first exposure to antique radios, and a place we try to return
to every year or so - we live on the west coast now. Lots
of things year round, but of special note is their annual convention
November in Mesquite and annual spring auction in Mid-March.
