Early radio 1920-1929 atwater kent model 10

In an age where we have instant access to news and intertainment it is hard to imagine not only the thrill of hearing programming from hundreds of miles away but the effort required. Early radios required multiple battery types, long outdoor antennas, real earth-ground connections and lots of patience.

Restored versus Ruined

Original condition radios are becoming harder to find every day. Whenever possible original wood finishes should be cleaned and touched up. Avoid the urge to ever start sanding original wood veneers.

Don't plug that garage sale find into the first outlet available before checking the old capacitors. Toasted power transformers present a much more difficult restoration.
