I replaced all capacitors. There was also a bad output transformer and the field coil speaker was in bad shape so I used a resistor to substitute for the field. The volume control still needs some work. This radio uses the old style tubes such as the type 80 predating the octal tubes. It is a superheterodyne and has 4 tubes but the 6F7 IF tube also has the detector and first audio stage.
