Greetings.
I restored an S19R a couple of years ago and wrote an article about it. It is
posted on the Hallicrafters Collectors International website at
www.w9wze.org
Look in the "Restorations" section.
Fine radio for 1938. If you are going to keep it I would recommend replacing
the electrolytic and a all of the old wax capacitors. It will then keep playing
for another 65 years.
