Looked strange to me as well. It could be something as stupid as the guy in purchasing at the factory got a really good deal on 35C5s, that was so good that the extra resistor cost added was still less than 50C5s.
Or maybe this radio was intended for use in Japan around the time we were still occupying them after WW2. Their powerline is 100VAC vs our 120VAC, so a 35C5 instead of a 50C5 would work. If that's the case, I'd change the 35C5 to a 50C5.
