That is one strange tube complement!
It looks like the typical "all American five-miniature tube" arrangement, only the 50C5 in the audio out has been replaced with a 35C5.
It use to be common to use the 35C5 in slightly more expensive radios with a three-gang tuner and an RF stage (usually another 12BA6).
Here, using a 35C5 in place of a 50C5 necessitates a ballast resistor whilst slightly reducing audio output - with no benefit!
