Postwar American Television
Wintermute Radio Service Shop
Just after World War Two radio shops started setting up for television repair, even before sets started being manufactured after the war. Pictured below is a 1946 shop in New Jersey. The CRT is a 14AP4; the chassis is from a DuMont 180 or similar set. On the top shelf is the test equipment, including a Philco television oscilloscope.
In 1946 you could buy a 9AP4 for $62.50; a 12AP4 for $75, and the "new" 5TP4 projection tube for $70.
